Roof Pressurization Fan

The height of the fan support legs are factory supplied to suit all stairwells and shaft openings.

Roof pressurization fan.

The roof level stairwell door pressure difference is very large due to the pressurized stairwell being in direct connection to the ambient pressure rather than the pressurized building interior. At s p we have a wide range of roof centrifugal and helicoidally fans for residential commercial and industrial applications. One static vent style is the turbine vent which uses wind to power its enclosed fan all it takes is a light breeze to rotate the blades and suck heat out of the attic view example on the home. In case of fire in a high rise building a stair pressurization fan spf uses clean outside air to pressurize the air in stairwells.

Stairways are fire escape routes nowadays stairwells have better fire ratings than the rest of the building. Pressed galvanised steel base cowls windbands are of plastic or galvanised steel. Our roof fans range offer models designed for ventilation of homes and small enclosures like the ecowatt ctb to roof fans of industrial application like the series tmpb tmpt designed to move around corrosive gases. Galvanised sheet steel housing with modern flange connections.

It is also a roof mounted assembly model. Also substantially larger stairwell fan speeds are needed when operating in conjunction with elevator pressurization indicating a strong interaction. Belt driven exhaust fans handle large volumes of air at low static pressures.

Neta twin series centrifugal fans. This fan series is specially designed for stairs and elevator pressurization. Stairwell only pressurization elevator only pressurization and coupled stairwell and elevator shaft pressurization systems all considered all simulations for roof mounted fans unless otherwise noted fan speed and average shaft temperature model iterated until the minimum pressure differences across doors are obtained. Smoke spill roof axial fan.

Whether exhausting air or bringing fresh air into a structure the calculation produced should help to figure out the size of fan s required to accomplish the air exchanges needed. Exhaust fans mount through a cutout in a roof or wall. Industrial and commercial smoke spill applications. Complete with a standby fan and motor for applications requiring standby facilities.

This fan calculator is typically used to calculate the cfm or cubic feet per minute of air exchange that may be desired in a building.
