ollution Control Equipment. It is tubes, envelopes or cartridges in AIL provides reliable and highly spreads all over the entire cross section of the bag 몭lter The gas moves up & passes through the bags, enters the clean air plenum through the top open end of the bags. During the passage of the gases through the fabric, the dust is retained on the outside surface of the bags As the 몭ltration proceeds the thickness of the dust layer on the fabric surface increases resulting in increase in pressure drop across the fabric This necessitates the cleaning of the bags. Since the air 몭ow is from outside to inside, the bags tend to collapse and are held by the wire cages, whose shape they acquire The compressed air passing through the solenoid valves injects air at very high velocity for a short duration. This produces a shock wave causing the bag to expand and dislodging the dust cake which falls into the hopper. This unit is generally meant to operate with a pressure di몭erential of 100-125 mmWG
OFFLINE PULSE JET BAG FILTER
The Bag House/Bag Filter is generic name of Air Pollution Control Equipment. It is designed around the use of engineered fabric, 몭lter tubes, envelopes or cartridges in capturing dust, separating dust or 몭ltration process. AIL provides reliable and highly
e몭cient Bag Filters and Bag House systems.

ADVANTAGES OF AIL PULSE JET BAG FILTER
Easy installation – Depending on size, unit is shipped fully assembled or in PANEL form for quick and easy 몭eld erection, low 몭eld labor cost. Provides design 몭exibility to address site-speci몭c arrangement
Enhanced Pulse System Design – Improved cleaning e몭ciency Reduced Pressure loss. Reduces compressed air use and power consumption.
Quick Bag Replacements – Snap band arrangement of 몭xing 몭lter bags and cages are designed for easy installation, quick replacement.
Minimal Maintenance – No internal moving parts hence maintenance is reduced. Dust collector shutdown is minimized
Increased Bag life – Filter Bag life is enhanced by optimizing the bag cleaning mechanism and by reduced compressed air usage.
On-line maintenance access – Eliminates forced outages for fabric 몭lter maintenance. Clean side maintenance minimizes personnel exposure to 몭y ash, dust etc.
Automated System – Periodic compressed air pulsing removes accumulated dust from the bags with cleaning frequency and duration adjusted by solid-state timers or PLC
