Aluminum Frame Primary Efficiency Dragon Skeleton Coarse G4 Air Filter Pre Washable Filter

Recommended applications:

The filter media structure of the pleated air filter is a V-shape pleat, which increases the contact area with air and therefore improves the dust holding capacity. The main material of the filter media is a composite filter cotton or double-sided bonding metal mesh, cardboard frame or metal frame are optional for the frame.

The air filter only weighs about 1kg and is easy to install and replace. Therefore, it can be widely used in pre-filter system for clean rooms, HEPA air filters, air compressors, central air-conditioning fresh air handling unit and ventilation systems, and computer rooms dedicated constant temperature and humidity air conditioning unit.

Technical parameters:

1.YJ-G3 (G3 class filter)

2.YJ-G4 (G4 class filter)

Structure:  The two-layer die cut cardboard or aluminum alloy frame

combines with the filter media to form the simple and strong structure. Meanwhile, the filter adopts a V-shape pleated structure, the material usage is three times greater than common air filter, so the dust holding capacity is greater.

Filter paper: Special blended by non-woven fabrics and synthetic fibers with a fluffy structure, large dust holding capacity and low initial resistance

Filter media: The filter media is closely combined with the protection grid and processed into a contour, equal spacing filter pleat layer by special process, allowing the air to pass freely and evenly, so that the dust can be uniformly adsorbed on the entire media, thereby achieving high dust holding capacity.

Protection grid: The grid is a galvanized grid or wire grid to increase the strength of the filter pleats, effectively weakens the pleat jitter during use, thereby reducing secondary pollution.

Cardboard frame: High-strength waterproof cardboard, each intersection and the filter media are closely connected, which enhances the filter's robustness and helps to maintain the flatness of the pleated filter media and the balance of the pleat spacing.

Aluminum alloy frame: 1.00mm thick aluminum profile enhanced by double-sided or single-sided galvanized protection grid support, can be repeatedly cleaned.
