5 inch Mild Steel Rain Cap

The 5 inch mild steel exhaust rain cap is a large industrial component for vertical exhaust stacks with a 5 inch (127mm) bore. This size is found on large generator sets, mobile and static crushing and screening plant, and high-output industrial engines where the exhaust stack outlet reaches the 5 inch specification. The gravity-operated hinged design provides fully automatic weather protection with no maintenance requirements — closing under gravity when the engine stops and opening without restriction under exhaust gas pressure during operation. The increase in price at the 5 inch size reflects the larger material requirement for this more substantial cap. The mild steel construction is suited to covered and sheltered environments including large generator enclosures, indoor plant rooms and covered crushing sites
