Positive outlet for the installation, must be carefully checked for every detail, the need to focus on is the height of the problem. You need to set the standards prescribed fire elevator pressure delivery outlet among manufacturers, and this fire elevator need to set up the hall, but it has provided a temporary evacuation of the type of buffer space, you can correct the air, can be external Fresh air is transported through the pipeline, the air vents to the right place. At present, a positive pressure in the outlet 南科莱 set is made of aluminum alloy combined with positive pressure air dampers with vendors supply outlet, can effectively and widely used in fire safety requirements for ventilation and air conditioning return air pipe at the outlet or inlet port, usually installed in the duct or duct end and side walls, the usual style of port to use, you can adjust the direction of air flow. It is possible to ensure that positive pressure air supply, to ensure that pressure delivery outlet wind epidemic is conveyed as required, rather than the instantaneous buffer incoming. Pressure delivery outlet mounting height, according to the specification, you must set the fire lifts, fire lift should have the front room, also known as the elevator hall and stairwell if it is combined, then called shared room, such as the front room when a fire evacuation provides a temporary buffer space, by partially into fire evacuation stairs between excessive, therefore, require such an air space of a certain degree of mobility, so-called positive pressure air, i.e. machines to the outside fresh air is piped into the ventilation requirements of this site, this is called positive pressure air. pressure delivery outlet from aluminum vent dampers for decorative surface and a combination of pressure delivery outlet, Texas manufacturers, widely used in the outlet of the fire safety requirements of ventilation and air conditioning of the return air duct or the suction port, usually installed in the duct or duct end and side walls, the usual style of port to use, you can adjust the direction of air flow.
