Application and design of primary filters

2022-07-28 Page view : 121 views

The primary filter is applied to the primary filtration of air conditioning system, mainly used to filter dust particles above 5μm. There are three types of primary filters: plate type, folding type and bag type, with paper frame, aluminum frame and galvanized iron frame as outer frame material, non-woven fabric, nylon net, activated carbon filter material and metal hole net as filter material, and double-sided sprayed wire mesh and double-sided galvanized wire mesh as protective net.

SFFILTECH-Professional Bag Filter manufacturer introduces you the application scope of primary filter: it is suitable for primary filtration of air conditioning system.

Purification G series coarse filter is divided into eight varieties: G1, G2, G3, G4, GN (nylon mesh filter), GH (metal mesh filter), GC (activated carbon filter), GT (high temperature resistant primary filter).

Inexpensive, light weight, good generality and compact structure.

● Pre-filtration of central air conditioning and centralized ventilation system

● Pre-filtration of large air compressor

● Clean return air system

● Pre-filtration of partial high-efficiency filtration device

● High temperature resistant air filter with stainless steel outer frame, high temperature resistant 250-300℃ filtration efficiency

This efficiency filter is commonly used for primary filtration of one air conditioning and ventilation system, and also for simple air conditioning and ventilation systems that only need primary filtration.

G series coarse air filters are divided into eight varieties, namely: G1, G2, G3, G4, GN (nylon mesh filter), GH (metal mesh filter), GC (activated carbon filter), GT (high temperature resistant coarse filter).

1、Large air permeability, low resistance, low energy consumption for operation.

2、Dense non-woven filter cotton filter media, effectively remove atmospheric dust particles, high filtration efficiency.

3、Aluminum profile outer frame or galvanized plate frame, surface protection net support protection, strong and durable, easy to install and beautiful.

4、Large dust capacity, long service life, high cost performance.

Application: Pre-filter for central air conditioning supply and return air outlets or equipment, the first filter barrier at the air inlet.

Design features and applications

1、GN nylon mesh primary filter: ultra-thin and lightweight, large air volume, small resistance, can be repeatedly cleaned and used.

Use occasions: clean room, clean room, central air conditioning, home air conditioning, purification workshop, primary filtration at the return air supply, special acid and alkali resistant places require ventilation filtration.

2、GH metal mesh primary filter: large air volume, small resistance, acid and alkali resistant oil mist and high temperature, effective removal of soot particles, can be repeatedly cleaned and used, long life, high cost performance.

Use occasions: central air conditioner primary filtration, clean plant, electronic workshop, special acid, alkali or high temperature ventilation filtration

3、GT high temperature resistant primary filter: imported long and short glass fiber filaments with good flame retardancy and chemical resistance, low hygroscopicity, can be used for a long time under 400℃ environment.

Primary filter occasions: generally used in clean room, dust-free spraying workshop, baking paint, spraying and other occasions requiring high air uniformity.

1、Large air permeability, low resistance, low energy consumption for operation.

2、Dense non-woven filter media, effective removal of atmospheric dust particles, high filtration efficiency.

3、Aluminum profile frame or galvanized plate frame, surface protection network support protection, strong and durable, easy to install and beautiful.

4、Large dust capacity, long service life, high cost performance.

SFFILTECH reminds you that the applications of top 10 primary filter are: aseptic room, clean room, central air conditioning supply and return air outlet or equipment pre-filter, the first filtering barrier at the air entrance.
