F7 Grade Pocket Bag Filter Synthetic Fiber Pocket Air Filter For Factory Central Air‑Conditioning & Clean Ventilation System

Product Overview

For industrial‑plant and clean‑workshop central‑air‑conditioning fresh‑air‑processing system, coarse‑filter alone cannot meet indoor‑air‑quality requirement, pocket bag filter acts as key intermediate‑stage filter‑element inside Air Cleaning HVAC‑filter product‑range. This F7‑grade synthetic‑fiber pocket‑bag‑filter adopts multi‑pocket bag‑type structure, synthetic‑fiber filter‑media, with large dust‑holding‑capacity and stable F7 filtration‑efficiency. It is installed inside air‑handling‑unit AHU box, intercepting fine outdoor atmospheric dust, pollen and industrial floating‑ash, protecting subsequent high‑efficiency HEPA filter‑elements from excessive dust‑load, widely applied for pharmaceutical factory, semiconductor‑workshop, food‑processing‑plant and large‑scale industrial‑building central‑ventilation‑system.

Basic Technical Parameters

Indoor‑Ventilation System Application Scenarios

Pharmaceutical‑factory air‑handling‑unit: pre‑filter + F7 pocket‑bag‑filter + terminal HEPA filter forms complete fresh‑air‑filtration‑chain; F7 pocket‑bag‑filter undertakes intermediate‑filtration task, intercepts most fine outdoor dust, greatly extending expensive terminal‑HEPA‑filter service‑life. Semiconductor‑manufacturing‑plant air‑conditioning‑system also uses large‑quantity F7‑grade pocket‑bag‑filters for fresh‑air‑purification. Large food‑beverage processing‑factory workshop ventilation‑system, commercial‑building central‑air‑conditioning‑units are also typical‑application‑scenarios. Different from industrial dust‑removal equipment which processes high‑concentration dusty‑gas, this product faces low‑concentration outdoor atmospheric‑fresh‑air purification, belongs to building‑HVAC ventilation‑category product, and can form complete‑filtration‑scheme together with panel pre‑filter and HEPA filter.

Core Product Advantages

Multi‑pocket bag‑type structural‑design provides large effective filtering‑area within limited AHU‑installation‑space, achieving big dust‑holding‑capacity and long‑service‑interval. Multi‑layer gradient synthetic‑fiber‑media structure, the pore‑size gradually‑changes from air‑inlet‑side to air‑outlet‑side, improving dust‑storage‑capacity and avoiding early‑blocking. Optional galvanized‑steel frame or lightweight aluminum‑alloy‑frame adapts different AHU‑box‑installation‑requirement. The product strictly follows ISO16890 classification‑standard for efficiency‑grading, filtration‑performance is stable in long‑term running. It is lightweight and convenient for on‑site‑replacement operation by maintenance‑workers.

Manufacturer & Factory Strength

Our air‑filter‑workshop produces full‑series HVAC filters, covering G3‑G4 coarse‑filter, F5‑F8 pocket‑bag‑filter and H‑grade HEPA high‑efficiency filter‑series. Each batch of pocket‑bag‑filters will pass efficiency‑sampling‑inspection according to ISO 16890‑test‑standard before leaving‑factory. We support non‑standard size customization for special‑size AHU‑box. Besides pocket‑bag‑filter, we supply complete‑set pre‑filter, V‑bank filter and HEPA‑filter matching‑supply. We can provide whole‑set ventilation‑filtration‑scheme‑consulting for engineering‑contractors of pharmaceutical‑plant and semiconductor‑factory industrial air‑filter consumables.

FAQ

Q1：What is the position of F7 pocket bag filter inside AHU air‑handling‑unit?
A1：It works as intermediate‑stage filter, installed behind G4 coarse pre‑filter and in front of HEPA high‑efficiency terminal filter, undertaking main fine‑dust interception work of fresh‑air system.

Q2：What is the difference between F5, F7 and F8 pocket‑bag‑filter grade?
A2：F5 is medium‑low efficiency; F7 is medium‑high efficiency for most industrial‑workshop ventilation; F8 is higher‑efficiency for strict‑requirement clean‑fresh‑air‑scenarios.

Q3：Can F7 pocket bag filter be cleaned and reused?
A3：Synthetic‑fiber pocket‑bag‑filter is disposable‑type generally; washing will cause irreversible decline of filtration‑efficiency, it is recommended to directly replace after reaching service‑cycle.

Q4：Can you customize non‑standard dimension F7 pocket bag filter for old‑type AHU‑box?
A4：Non‑standard‑size custom‑service is available, please provide AHU‑internal‑installation‑opening dimension drawing for confirmation.

Q5：What supporting HVAC filter products can you provide matching F7 pocket‑bag‑filter?
A5：We supply G3/G4 panel pre‑filter, V‑bank air filter and H‑grade HEPA filter, to realize one‑stop supply of whole‑set AHU‑filtration‑consumables.
