It has 70% greater suction power compared to PRC3 The search for a pump of this specification at this price took many years . Do not confuse these pumps with the ones used in vacuum cleaner based machines. These are laboratory standard scientific pumps which are quiet and efficient. . Set at 28 litres per minute flow for the pump ensuring even very dirty or warped records will be cleaned efficiently.The PRC4 EVO features a somewhat heavier-duty and quieter vacuum motor than the PRC3 (the PRC3's motor is already very effective and very quiet)
- A new drive system using very high torque motor .
- Three row needle roller bearing centre shaft making for use of the motor torque. This design is completely different to normal turntable bearings to allow long life whilst experiencing considerable force.
- Custom made motor gear box system to drive the cleaning arm.
- Custom made pump system
- Enclosed bearings (4 off) on cleaning arm. These are of the highest grade allowing freedom of movement whilst being considerably more durable than typical pick-up arm types. They also avoid contamination by liquids.
These improvements have been carried over into the PRC2 and PRC4 models, where applicable.
The famous Loricraft Cleaning System is perhaps the finest you can buy and is of particular value to professional studios, used record stores, or serious vinyl collectors that may have a huge investment in their record library. It does an incredible job of cleaning records that may have been poorly handled and stored in the past, or used records that are purchased from pervious owners who did not take care of the record.
Even though this product may be three times the price of some popular "wet system" cleaners, there are several design advantages to produce truly superior results. The Loricraft model PRC3 and PRC4 are handcrafted in the U.K. using only the finest custom made European components.
A bottle of L'Art du Son concentrate is included with the unit. This makes up 5 litres of cleaning fluid, enough for about 1000 LPs. Also included with the unit is a brush to apply the cleaning fluid.
Probably the best record cleaning machine in the world. You buy vinyl? You need a Loricraft - Dagodo Review
Even more important, the ingeniousness of the Loricraft's self-cleaning design ensures that you will have a clean, fresh record each time you use it, and that alone makes it hard to beat. - Danny Kaey Positive Feedback
So how good is it for Compared to the VPI, the Loricraft is whisper quiet, with only a very slight hissing sound when the vacuum is running. Since the unit is conducting static charge away as it is cleaning, none is left on the record. All of the fluid is suctioned back, leaving no residue, and no static charge. I found no improvement with two cleanings, thus; only one cleaning cycle is necessary compared to the two with the VPI. It is probably the same price you would pay for a new cartridge or tonearm, and will give you as much if not more sound improvement. But then I have gone crazy and have a Walker Proscenium turntable resting on a Arcici Suspense System with a Kondo IO-J cartridge, so you can see how much I am willing to spend for great analog reproduction. Are you? Positive Feedback
The Loricraft PRC 3 is not a cheap machine but because of its expensive design and construction, and its "bulletproof" build quality, it is not expensive at all (...or worth every penny.) It may be a little larger than other machines but very efficient, quiet, but doesn’t require frequent, expensive servicing.
Compared to all machines: Loricraft PRC 3The building quality shows that it is made with loving care.
It is very quiet, very thorough in its performance, and has no need for extraordinary maintenance. In addition to that it cleans every size record, including 16” electrical transcriptions. - Audio review
A bit of history . . . .
The Loricraft PRC3 is based on the work of the late Percy Wilson, Technical Editor of the Gramophone Magazine in England. The prototype (hand made) machine was demonstrated at the Buxton Hi-fi show in the 1960's and drew quite a bit of attention for it's ability to thoroughly clean a record. This scheme has since been used by two companies in similar products.
The design was improved and modernized using state-of-the-art components and by Loricraft Audio. Thousands of units are now used around the world by leading record studios, record dealers, and serious collectors. The product is also very simple to use.
How Record cleaning machines work . . . ..
1. The popular priced record cleaning machines use a basic, low cost Shop Vac "wet/dry" vacuum motor to remove the cleaning fluid from the record. These type motors are for intermittent use only and will seriously overheat if run continuously. Because these motors develop a high RPM in order to develop a net 27 pounds per square inch vacuum at the nozzle, they are extremely loud. An optional cooling fan installation kit is offered by the manufacturers for continuous operation at a cost of about $100.
2. A Vacuum Pickup "Wand" extends over the playing surface of the record and sucks up the fluid applied to the record. Velcro-like strips are cemented to either side of the vacuum "slot" of the pickup tube. Manufacturers of these type machines recommend cleaning the "lips" with a toothbrush after every few cleanings to keep grit, chemical pollution, and dirt from being transferred to the next record being cleaned. If not done religiously contamination from one record can be transferred to the next, and the next, and so on. Manufacturers recommend the Pickup tube be replaced after 200 cleanings (400 sides). The cost of the new tube is between $50-$100.
3 .When vacuuming the cleaning fluid from the record surface two revolutions of the geared down turntable are recommended. More than two turns can cause the vinyl to develop a static charge that will attract dust and particles similar to those just removed. This is due to the friction of the Velcro like material against the vinyl compound.
4. Old records that are slightly rippled or warped are not cleaned fully because the long "wand" nozzle does not lie flat on the record. A slightly warped record may look like a clamshell when cleaning one side, and has a "hump" in the middle when cleaning the other side. The low parts of the record cannot be reached by the flat vacuum tube.
5. Because modern Lp records have a raised outside rim and raised label area to prevent scratching of the records when played on a record changer, the vacuum pickup tube does not make good contact with the beginning of the first band of these records. This is usually the dirtiest part of the record due to fingerprints and airborne particles that collect at the opening of the record jacket.
The Benefits of a Loricraft Machine
All major components are hand-made - in house
The size of the unit:
Width - 54.6cms -including collection jar
Depth - 40.6cms
Height - 30cms
Very quiet, making it domestically acceptable for home use.
Our brush goes to the top of the grooves for intital cleaning and works the fluid in to the grooves, loosening any contanimants.
The nylon protection thread, which wraps around the nozzle, has two functions. It prevents the ptfe nozzle from contacting the record, and leaves an air gap to allow the vortex of the nozzle (suction) to remove all the fluid and debris from the record grooves - leaving it clean and dry.
We use a fresh application of cleaning fluid for each side of the record.
It takes less than two minutes to clean and dry a single record side.
Loricraft machines can clean 7", 10", 12" and 16" records. Loricraft Audio also build the specialist PRC5 - to clean 20" records
Loricraft machines can be found in National Sound Archives, professional Recording Studios, and Record Stores as well as being used by enthusiasts around the world.
All machines come complete with a bottle of L'Art du Son Cleaning Fluid, a brush, thread, collection jar and detailed instructions, as well as a full 5 year Warranty.
How is the Loricraft different?
1. The PRC3 uses an expensive European industrial vacuum motor that can run 24 hours a day without overheating. The vacuum system is so quiet you may enjoy playing your records while cleaning others, and you will not wake up the neighbors when the PCR3 is working. Instead of attempting to clean the record in one pass, as the other machines do, the Loricraft has a vacuum arm similar to a phono tone arm that glides over the record. One side of the record is cleaned in less than a minute. The vacuum arm is driven by a separate motor assembly using a clever coupling system.
Special cleaning thread is used.
#30 nylon filament threads out of the center of the nozzle into the evacuation tube.
2. The nylon nozzle tip of the vacuum arm does not touch the record. A fine filament nylon thread threads through the center of the arm and nozzle that allows the arm to lie very close the record. This un-calendared thread acts as a "ski" to support the arm and keep it a small fraction of an inch from the record. In fact, the distance is the thickness of the 30 gauge thread. Terrific suction is developed at the nozzle because of this proximity effect. To illustrate this, use your home canister vacuum cleaner. Remove any attachments from the hose and, while the cleaner is running, slowly move the hose close to the palm of your other hand. As you approach contact, the air velocity will dramatically increase and you will feel the powerful suction. That's how the Loricraft vacuum arm works. It is high intensity, local suction that is not distributed over the whole record (globally). The arm will "ride" up the rim of the record to assure the beginning track of the record is perfectly cleaned.
3 .The vacuum arm is adjusted to about 2.5 grams pressure. A phono tone arm pressure gauge may be used to adjust the exact weight of the arm. The vacuum arm is easily removed from the brass holding cylinder on the plinth by pulling it straight up. The arm drive motor has a circular magnet attached to its shaft that mates to a circular magnet on the bottom of the arm assembly. This permits easily moving the vacuum arm without any damage to the motor, through this unique coupling method. The suction nozzle adjusts automatically to records of any thickness including the new 180 /200 gram audiophile releases.
Allow 1/4 turn of loose thread for each record.
Nylon cleaning thread feeds the delivery tube and is "vacuumed" out the evacuation tube.
4. The turntable platter moves at 80 RPM which exposes the maximum surface of the record to the moving vacuum arm. The record is absolutely dry because of this action.
5. Before cleaning another record pull out a ¼ inch of fresh thread from the thread feed tube. This assures clean thread is in contact with the record and will not transfer contamination from the last cleaning. The excess USED thread is sucked into the fluid vacuum tube and is deposited in the USED fluid reservoir jar.
Do not force brush into record grooves.
Nylon bristle brush is held lightly on spinning record.
6. The top cover of the PRC3 is made of a tough acrylic material that makes cleaning extremely easy. If you splash cleaning fluid on the machine, simply wipe it up with a tissue.
Operation switches are conveniently located.
7. The three control switches on the top panel (Turntable, Arm, and Pump) are jacketed with a rubber cover to keep fluids from corroding the metal switches.
Wash spent fluid bottle ocassionally.
When the spent fluid bottle is half full, remove and wash bottle
8. A "spent" cleaning fluid reservoir jar is attached to the side of the machine by an expandable strap. This makes removal very easy in order to dispose of the fluid. The fluid level is clearly visible and the bottle should be "dumped" every month or so, depending on frequency you use the cleaning machine.
9. The nylon thread spool contains 100 yards of media (the length of a football field) and, with ¼ inch used per record, should last for thousands of record cleanings. Only clean thread should touch the record.
10. A Nylon bristle brush (to drive the fluid into the grooves until fully wetted), and a spool of nylon thread it furnished with each system. Why nylon? It's anti-static!
11. Any of the popular record cleaning solutions that work with other brand machines may be used with the Loricraft System. We include a free bottle of ecord cleaning solution with each machine to sample.
