In ventilation systems, a jet fan, also known as an impulse or induction fan, ejects a stream of air that entrains ambient air to circulate the ambient air. The system takes up less space than conventional ventilation ducting and can significantly increase the rates of inflow of fresh air and expulsion of stale air. [26]
An air handler, or air handling unit (often abbreviated to AHU), is a device used to regulate and circulate air as part of a heating, ventilating, and air-conditioning system. [1] An air handler is usually a large metal box containing a blower , furnace or A/C elements, filter racks or chambers, sound attenuators , and dampers . [ 2 ]
An auxiliary ventilation system takes air from the flow-through system and distributes it to the mine workings via temporarily mounted ventilation fans, Venturi tubes and disposable fabric or steel ducting. Auxiliary fan and duct systems may be either forcing systems, where fresh air is pushed into mine headings, or exhausting systems that draw ...
In Bangladesh, it is unusual for a female to design a mosque – Bangladeshi women rarely even enter a mosque, praying instead at home, since few mosques have dedicated sections for women.

In the case of an ideal lossless fan system (i.e. =) the SFP is exactly equal to the fan pressure rise (i.e. total pressure loss in the ventilation system). In reality the fan system efficiency is often in the range 0 to 60% (i.e. <); it is lowest for small fans or inefficient operating points (e.g. throttled flow or free-flow). The efficiency ...
A typical whole-house fan, with louvers closed when not operating.
