Product Description
The G4 Pre Filter is a primary plate-type air filter installed at the upstream inlet of a purification or ventilation system, ahead of the fine and HEPA stages. Its job is not to deliver absolute cleanroom air itself, but to take the bulk of the coarse dust load - lint, outdoor particulate, workshop carryover - before that dust reaches the much more expensive downstream high-efficiency filters. The element uses an aluminum alloy housing for a rigid, lightweight frame that drops into a standard 46mm holding grid, and the pleated media pack is accessed from the same face used by other primary plates in the ductwork. Because it sits first in the airflow path, the G4 pre-filter sees the heaviest dust concentration and is designed to be inspected and replaced as a low-cost consumable rather than serviced like a terminal element. Its effect on the system is practical: it extends the service life of the downstream HEPA filters by absorbing the large-particle load that would otherwise clog them quickly, and it keeps the pressure drop of the whole air-handling system stable between HEPA change-outs. Available in plate sizes 295x595x46mm and 595x595x46mm, it suits standard primary-filter grids used in building ventilation and workshop pre-filtration.
The buyer pain this pre-filter addresses is the cost of premature HEPA replacement. A high-efficiency element that loads up with coarse outdoor dust reaches its end-of-life pressure drop far sooner than it should, and HEPA elements are the expensive part of the system to change. Jinye supplies the G4 pre-filter as a low-cost, standard plate that takes the first hit, so the downstream HEPA sees only the finer fraction and lasts through a longer service interval. Because the pre-filter is the consumable in the chain, it is produced to repeatable standard sizes (295x595 and 595x595 at 46mm) that drop into existing grids, and volume orders for repeat replacement stock qualify for tiered pricing - a direct cost lever for procurement teams running large installed cleanroom fleets.

Applications
- Building make-up air and general ventilation. Installed at the fresh-air inlet, the G4 plate captures coarse outdoor dust and lint before it enters the downstream filters, keeping the whole duct and fine stages cleaner.
- Electronics, pharmaceutical and food workshop pre-filtration. As the first element in workshop purification systems, it takes the bulk particulate load so the controlled downstream filtration sees a lighter, finer stream.
- Upstream protection of terminal HEPA elements. By absorbing large-particle carryover, it extends the working life of the expensive HEPA filters and stabilizes system pressure drop between HEPA change-outs.
Customization
Primary plate sizes follow the 295x595x46mm and 595x595x46mm standard grids. Configurations are discussed per project within the existing range; the company does not develop brand-new filter designs.
Packaging & Transportation
Shipped EXW (ex-works). Each filter passes a pre-delivery inspection before dispatch. Units are packed in standard protective packaging for transport. Jinye does not arrange ocean freight, air freight, courier or DDP/CIF delivery.
FAQ
Q: What is your MOQ for pre-filter plates?
A: For filter equipment, order quantities are discussed per project rather than a fixed square-meter minimum; contact us with your required sizes and quantity.
Q: Do you offer discounts on repeat pre-filter orders?
A: Yes, volume discounts are available for larger and repeat orders, which suits procurement teams buying replacement stock.
Q: How do you control pre-filter quality?
A: We source quality raw materials, monitor production in process, and carry out a pre-delivery inspection of each finished unit.
