When you purchase exhaust air box problem needs to be considered in the situation now exhaust wind chassis to further growth and application of its choice of users are constantly grow, then we need to consider when purchasing their problems are what does? Coherent skilled personnel to make this issue a further report to us, first check the exhaust duct observe rigid chassis modulating valve opening and closing means is not strong, sharp, clear symbol of the opening and closing viewpoint. Secondly, the police at the check manually turn lights and voltage, current meter operation is not normal, all things exhaust wind chassis parts are no different from the sound of the wind chassis sales, three-current value is not balanced. Three times to check off on the remote observation points are not exactly secure. Another deal to buy exhaust wind chassis, and another that required meticulous, its pressurized smoke exhaust fan pressure value should be the worst of the loop held accounting system, exhaust air box, and make sure residual pressure value in the stairwell 40 ~ 50Pa. Also resolved the meaning of the contents of the report hope that, in the majority of users can buy in the future, play some appropriate funding. Cabinet centrifugal wind chassis quality and security cabinet centrifugal wind chassis, cabinet centrifugal wind chassis quality is guaranteed. Cabinet centrifugal wind chassis receiving ancestors low noise centrifugal double suction fan, is equipped with a coarse atmosphere filters, in effect filter about sub-efficient filter, put in the (insulation) sound-absorbing panels and the like by the vibration damping rubber pad with low noise, vibration small, small size, light weight, air volume, variable speed, variable air volume, easy to operate, the wind chassis, modulating motor, site easy accessibility features, and has a silencer and atmosphere filtration. Equipped with electronic control box, remote control. Wind chassis series can be used for a pressurized ventilation system; or directly as an exhaust fan; wind and for mixing air box and use air power source. That the wind chassis requires gas, fire ventilation wind chassis, no corruption and natural properties; non-sticky material. Wind chassis has been widespread use in air conditioning and ventilation projects. After the wind chassis destination of fire smoke, equipped with two-speed motors, both at low speed ventilation, but also fire smoke at high speed, it is a machine with two.
