W Type-High Efficiency Particulate Air Filter(0.3μm)


Capturing efficiency: HEPA 0.3μm - 95%, 99.97%, 99.99%

This is the only nation-wide product which adopts smoke tests with PSL (0.3µm¡BDOP 0.3µm) and testing equipment for X-Y leaking scanning and penetration rate. The overall use of X-Y computer's fully automatic operation results in a seamless high-pressure airtight pad. The surface is smooth and glossy, never collects dust and has a damp-proof function.


Filtering element: filtering elements of the products are arranged in a V shape, leading to a low degree of damage even if the products come under pressure. They are also used in a working environment with plenty of wind.

Filtering material: the world's top quality incombustible water-proof glass fiber paper, with original fitting (imported from America) is used.

Framing material: galvanized iron sheets or chipboard are employed.

Purpose: an equipment with high wind amount and zero-dust; a system with adaptable, energy-saving air conditioning; inside an air conditioning box for a humid working environment.

The product is made in a zero-dust factory of Class 1000 degree cleanliness.
