1. large effective filteration area, low resistance and long service life;
2.material of AZL/1 type can be burned 100%and this accords with the requirement
of environment;
3. occupy small space and be suitable for the central air-condition system with compact
 structure;
The AZL/1 in AZL series filters applies the special hyperfine polyproplylene fiber.
 All the material of AZL/1 filters can be burned, which is in favor of environment and
rubbish disposal. The filtering material of AZL/1 is not easy to be damaged an unit
price of filters are relatively low.
The AZL/2 in AZL series filters applies the traditional fiber galss fliter paper. The
performance of the filters which are made of this kind filter paper are stable and with
high ability of holding dust.
The AZL/3 in AZL series is one kind of shock resistance and high reliablity filter. The
frame is metal material and there is metal protective net behind the filtering material.
This filter are mainly used in the filtering of the inlets of turbines and centrifugal
air compressors
