At s p we have a wide range of roof centrifugal and helicoidally fans for residential commercial and industrial applications.
Roof pressurization fan.
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.
Stairways are fire escape routes nowadays stairwells have better fire ratings than the rest of the building.
This fan series is specially designed for stairs and elevator pressurization.
In case of fire in a high rise building a stair pressurization fan spf uses clean outside air to pressurize the air in stairwells.
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.
Exhaust fans mount through a cutout in a roof or wall.
The pressurized air helps people escape the fire and firefighters battle the fire.
Complete with a standby fan and motor for applications requiring standby facilities.
The height of the fan support legs are factory supplied to suit all stairwells and shaft openings.
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.
Industrial and commercial smoke spill applications.
Direct drive exhaust fans have their motor mounted on the fan shaft so they are more compact and have fewer moving.

Also substantially larger stairwell fan speeds are needed when operating in conjunction with elevator pressurization indicating a strong interaction.
They run more quietly and allow greater control over fans speeds than direct drive exhaust fans.
Pressed galvanised steel base cowls windbands are of plastic or galvanised steel.
Smoke spill roof axial fan.
Belt driven exhaust fans handle large volumes of air at low static pressures.
It is also a roof mounted assembly model.
Galvanised sheet steel housing with modern flange connections.
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.
