● High filter efficiency

● Large dust holding capacity

● Low resistance

Product Introduction Product Details Performance Parameters Industrial Applications

Primary efficiency filter cotton has the characters of economical and practical, low initial resistance, high dust holding capacity, resilient, safe and environmental friendly. It is convenient to use. 


Material: chemical fiber

  1. Primary efficiency filter cotton width mainly has: 1250MM, 1400MM

  2. Divided by thickness mainly has: 5MM, 10MM, 15MM, 20MM and so on

  3. Resistance: less than or equal to 50 Pa (wind speed: 1.0 M/S), filter efficiency of 2.0 micrometers (%): more than or equal to 50 %( wind speed: 1.0 M/S) 

Primary efficiency filter cotton is used on the front end of the filter which can eliminate fiber dust, willow, and sand, cleaning dust and some other more than 5 micrometers larger particles, so as to protect the latter part of the filter. Changes are the most frequent. It suggests that 3-5 days or a week change the filter and follow site engineer’s experience.
