Application and design principle of primary filter

Tyd: 2022-07-14

The primary filter is used in the primary filtration of air conditioning system, mainly for filtering dust particles above 5μm. There are three styles 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.

Adaptation range ofSFFILTECH primary filter: It is applicable to the primary filtration of air conditioning system.

SFFILTECH G series coarse efficiency filters are 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 efficiency filter).

Low price, light weight, good versatility and compact structure.

SFFILTECHprimary filters are mainly used for

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

● Pre-filtration of large air compressors

● Clean return air system

● Pre-filtration of partial high-efficiency filtration devices

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

Features of SFFILTECHprimary filter.

This efficiency filter, commonly used a primary filtration of air conditioning and ventilation systems, is also suitable for simple air conditioning and ventilation systems that require only 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 operating energy consumption.

2、Dense non-woven filter cotton 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.

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

Design features and application ofSFFILTECH primary filter

1、GN nylon meshprimary filter: ultra-thin and lightweight, high air volume, low resistance, can be repeatedly cleaned and used.

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

2、GH metal meshprimary 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 resistant ventilation filtration

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

Use occasions: general primary filtration, hot air type high temperature oven air filtration, dust-free spraying workshop, coating factory high temperature oven air filtration

4、Purification project GL zenith equal-flow filter: thin thickness, large air volume, high filtration efficiency up to F5, F8 level, good equal-flow performance.

SFFILTECH primary filter use occasions: clean room, dust-free spraying workshop, baking paint, spraying and other occasions that require high air uniformity.

1、Large air permeability, low resistance, low operating energy consumption.

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

3、Aluminum profile 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.

Applications: sterile rooms, clean rooms, central air conditioning supply and return air outlets or pre-filters for equipment, the first filtering barrier at the air inlet.
