No Loss Exhaust Stack Cap

No other stack termination will give you the positive effects for pollution control that the no loss stack head will.

No loss exhaust stack cap. So if the main stack is 12 inch diameter you should use a 54 inch section of 14 inch diameter for the cap. See i said you explained it better. 4 times 12 48 plus the 6 inch overlap 54. Nordfab stackheads are designed to be used when exhausting fans or stacks through a roof.

Style 190 no loss stack head. The exhaust source is offset from the stack and drainage features in the stack direct any water flow away from the exhaust source. Flanged end provides for wire guide security. And the cap length should be 4 times the diameter of the main stack.

You will see that the assembly is made up of two pipes. Most other solutions drastically reduce exhaust velocity and some actually force the exhaust down where it can linger build up and get drawn into hvac or fresh air makeup systems. Now available in galvanized aluminum stainless and stainless with optional no. This configuration is based on the principle that rain falls at an angle.

Exhaust stacks do not use weather caps. Sometimes the termination can even be turbulent enough to compromise the exhaust system. Stackheads eliminate back pressure on the fan while providing weather protection. Unmatched quality and customer service no other duct manufacturer understands more about putting a working duct system together tailoring it to the customer s current and future needs communicating how to install it then manufacturing it correctly and delivering it on time.

No loss stack head provides weather protection while it eliminates back pressure on the fan. To correct this the central exhaust duct is surrounded by the larger duct of the no loss stack and extends up higher than the central duct and is. No loss stackheads protect exhaust fans from weather increased resistance causes the fan to use additional power to maintain the calculated cubic feet per minute cfm rate required for the system. Any fume hood mechanical system without one is incomplete.

The contaminated air will continuously meet with resistance at the end cap quickly resulting in corrosion of the ductwork and a tumult of eddying fumes. The inner stack is surrounded by an outer stack with space between the two. Losses associated with them may also have other system effects no loss stacks stack diameter d 1 stack height 4d 6 d duct diameter maintain discharge velocity of 3 000 fpm weather cap no loss stack d.
