The document discusses particulate control group 2 and their gravity and momentum collector. The collector uses settling chambers and louvers to admit air while keeping out rain and noise. Louvers have adjustable or fixed slats that change the direction of gas streams. Larger particles do not change direction and settle in the dead air space, making it a precleaner for more efficient collectors.

2. GRAVITY AND MOMENTUM COLLECTOR
◦ SETTLING CHAMBERS

3. ◦ LOUVERS
- Is a window blind or shutter with horizontal slates that are angle to :
 admit like an air
 To keep out rain
 Direct sunshine and noise
- The angle of the slat may be adjustable, usually in blind and windows or fix

4. ◦ Used a fixed buffle plate that cause the conveying gas stream to make a sudden change of direction
◦ Large diameter particle do not follow the gas stream but continue into a dead air space and settle.
◦ Used as precleaners for more efficient collector.
