carton frame synthetic air filters / paper frame air filter

Applications:

l Pre-filtering of central air-conditioning and central ventilations systems

l Inlet pre-filtering of turbines and air compressors.

l Household central air-conditioner

l Special uses such as nuclear and national defense industries.

Features:

Filtering Materials: chemical fiber

Efficiency grade: G3, G4

ABL board filters: aluminum frame, washable, replaceable filtering material

Replaceable filtering media: Customers can change filtering media conveniently. Customers can save cost of spare parts and get rid of the trouble of transportation and storage.

Filtering efficiency:

Filtering efficiencies of ABL has two kinds: G3 and G4. The corresponding efficiency of weight-counting method is 80%-90% and efficiency of colorimetry method is 40% . Filters with these efficiencies as commonly used in the first stage filtering of air-conditioning and ventilation systems, as well as in air-conditioning and ventilation systems that have only one-stage filtering.

The different model is as following:

Model	Class	Size (mm)	Net media(m2)	Rated airflow(m3/h)	Resistance Pa, Via rated airflow 70% 100% 120%
ABL6605-G3	G3	595x595x46	0.6	3600	65	85
ABL3605-G3	G3	290x595x46	0.3	1800	65	85
ABL6610-G3	G3	595x595x96	1.37	3600	30	55	75
ABL3610-G3	G3	290x595x96	0.63	1800	30	55	75
ABL6605-G4	G4	595x595x46	0.6	3600	70	110
ABL3605-G4	G4	290x595x46	0.3	1800	70	110
ABL6610-G4	G4	595x595x96	1.37	3600	45	75	95
ABL3610-G4	G4	290x595x96	0.63	1800	45	75	95

Notes: We can also produce board filters that have the size of G4 and the efficiency of G3.

We can produce ABL filters of all sizes according to requirements of customers. But the filters height shall not be than 620mm,

and thewidth not be than 900mm duo to the limited of transportation.

The green ABL board filter filtering efficiency is G4, the white ABL board filter filtering efficiency is G3, Also we offer the metal-mesh ABL board filter.
