How to install the air filter frame?
Air filter frame installation is to have a certain law, it is based on modular air handling unit to deal with the different needs of the air, there is only installed early effect of an air filter, there is the initial installation, the effect of two air filters , But also the installation of early, medium and high (sub-high) efficiency of three air filters. At present in the modular air conditioning units used in the initial, the effect of the installation of air filters, air filter bag is usually set in the first metal filter material made of the support frame, and then set in the support frame Of the air filter installed in the unit fixed on the inner wall panels dedicated to install the air filter on the frame. No matter what way to fix the air filter mounting frame must be strong enough to withstand the operation of the unit due to the air filter resistance caused by wind pressure, the size of wind pressure recommended by the maximum value.
Install the primary and secondary air filter mounting frame, the attention frame should be perpendicular to the wall, should also take into account the gap between the frame and the sealing wall to prevent air short-circuit (that is, air is not processed by the air filter And leaks out of the target by the frame and the panel J). Note that the air filter in the installation of its surrounding should be smooth and take pressure measures to prevent the leakage around the filter. Air-conditioning system used in the early effect of air filters, mainly for filtering more than 10p_m of dust particles, the mass efficiency of 40% to 90%, for the particle size o.3 p_m dust particles, the counting filter efficiency Less than 20%, the initial resistance is generally 20 ~ 30Pa, the filter speed is generally 0.5 to 3. Om / s; efficiency air filter is mainly used to filter 1 ~ 10 pm dust particles, the filtration rate is generally o. The filtration efficiency is 45% ~ 98%, the counting efficiency is 20% ~ 90% and the initial resistance is less than lOOPa for o.3tim particle.
