GL320 Self-cleaning High Efficiency Air Filter Device.　

Research & Development

GL320 Self-cleaning High Efficiency Air Filter Device was firstly applied in Chinese Aviation Industrial. Its research and development began at July 1982 and ended at December 1988.

GL320 Self-cleaning High Efficiency Air Filter Device was developed by Chinese Aviation Industry. The new type high efficiency filter made by us can meet all technical requirements of furnace blast and air compressor. The performance is nearly the same with overseas similar products and its initial pressure is lower than America Donaldson filter.

Application

 GL320 Self-cleaning High Efficiency Air Filter Device combines with steel shell, W-140 type venture and pulse self cleaning system. It is a matched product of industrial gas turbine, large air compressor, and furnace blast.

Performance Advantage

After test, GL320 Self-cleaning High Efficiency Air Filter Device performance is as below:

●Dust concentration: ≤0.5mg／m3

●Dust size ≤2μm 　　

●Initial Pressure <150Pa(under rated flow) 　　

● able to self-cleaning. Operating with pulse jet system can keep the whole device working in an circumstance lower than 600pa resistance in long term.

●noise reduced>15dB(A) 　　

●Strictly structure, easy for installation and maintenance

●wonderful water-proof 　

●GL320 Self-cleaning High Efficiency Air Filter Device can keep working after clean dust automatically or manually for many times.

Self-cleaning System　　

High Efficiency Air Filter Device self cleaning system include two parts: impulse puff and blow system, pressure difference inspection and control system, the former consists of compressed air supply pipeline, compressed air gas bag, electromagnetism impulse valve and puff blow pipe; while the later contains measure and control instrument in functions of minute-pressure difference measure sensor and pressure difference inspection, impulse control and transfinite alarm, and etc.

Impulse puff and blow system, electromagnetism impulse valve

Electromagnetism impulse valve contains impulse valve（differential gas valve）and guide valve（control valve）. The valve composition is made of aluminum alloy through pressure casting and surface treatment which possesses the function of corrosion protection.

Its technological qualification should meet the following requirement

For self clean system, its design and assembly should meet the following requirement:

Seal reliable the joint of Gas bag, electromagnetism impulse valve and puff blow tube.

Compressed air supply pipeline should set oil gas separator and filter to ensure clean air supplied, while filtered air should eliminate oil, water and residue;

Gas bag bulk should keep electromagnetism stably supply gas, usually 8 or 10 electromagnetism impulse valve as a group.

Micro pressure difference sensor and control checking instrument should meet the following requirement:
