Pre-filters tit for air-conditioner`s first filter, To filter the 5μm` dust mainly. The profilter has three types named plate,told and bag shape ,The paper frame ,aliminium frame or galvanlze material are used,The filter material can be have no-spun cloth,nelon,active kryptol and steel net etc.

South constructs at the beginning of effect air strainer's characteristic which the treating plant Limited company produces: Moderately-priced, the weight is light, the versatility is good, the structure is compact.

● ZNCX-A(B)P uses in

● central air conditioning and centralism ventilation system pre-filtration

● large-scale air compressor pre-filtration

● pure return air system

● partial highly effective filtrating equipment pre-filtration

● the activated charcoal filter may except the air in unusual smell, pollutant, the improvement air-conditioning system air supplies quality and so on ammonia.

● thermostable air strainer, with stainless steel outer edge, thermostable 250-300℃

Filters removable expects REPLACEABLE MEDIA

 The user may replace voluntarily conveniently filters the material, may save the spare parts expense for the user, and reduces the transportation and the warehousing trouble.

   Filter efficiency EFFICIENCY

       The ZNCX-A(B)P filter efficiency has G3 and the G4 two kinds, the correspondence records heavy method 90% and the color method 40%. This kind of efficiency filter commonly used in air conditioning and ventilation system's primary filter, is also suitable for only needs the first-level filtration the simple air conditioning and the ventilation system.

      Finally resistance FINAL RESISTANCE:

      Suggested that the AP filter's resistance finally is 250~300pa.

      Suggested that the BP filter's resistance finally is 200~300pa.

      Size DIMENSIONS:

      The filter depth has 21mm, 46mm and the 96mm three kinds, the corresponding nominal depth 1 ", 2 " and 4 ". The filter Gao Hekuan first preferred dimension is 595mm, the corresponding nominal size 24 ".
