lift pressurization fan

Pressurization fans draw in outside air, send the air through the ductwork to staircases and lift lobbies to provide pressurization. The pressurization fans are usually located near the exterior wall in dedicated mechanical rooms. A pressurization fan duct connection starts with a weatherproof external louvre that comes with an insect screen.

Jan 06, · Pressurization fan makes the escape route pressurized so it forces the smoke and push it back and enables person to escape. In these calculation excel sheets, you will get the CFM for the pressurization fan for the stairwell and for the elevator lobby.

The purpose of the pressurization is to prevent the entrance of smoke to the fire escape fans are available for ladder and lift pressurization purposes.

Lift Pressurisation Fans are need of the hour, they are used to pressurise the lift shaft. These Fans play a vital role in safety during a fire. These are 

The pressurisation system will be sized to according to above mentioned flow and between 20-50Pa pressure. Anything more will effect the opperation of elevator doors and

Pressurization fans for the elevator hoistways were selected to maintain a pressurization difference of 0.10-0.25" W.C. relative to the rest of the building with all hoistway doors closed. An exhaust fan's static pressure, also known as its pressure drop, describes the resistance the fan must overcome.

Elevator shaft and stairwell shaft-pressurization systems are studied as means of and be actively distributed throughout the building by the fan system.
