Clean operating room air filter selection requirements! Is crucial, whether directly affect the operating room cleanliness standard.
1. Various filters in the clean operating room to purify air conditioning system should be a throwaway.
2. All the air filter shall not be used with wood products;
3 there should be no pungent taste of the finished product;
4 air filters use air volume shoulds not be more than 80% of the nominal air flow.
5. Electrostatic air purifying device shall not be used as final purification facilities of clean air-conditioning system.
6. When the concentration of air supply outlet arrangement, not stage filter appropriate USES sodium flame method efficiency is not lower than 99. 99% of the class B high efficiency air filter; When the tuyere scattered arrangement according to the conventional levels Ⅳ clean operating room and Ⅲ, Ⅳ clean auxiliary level at the end of the filter can be used for acuity 0. 5 microns atmospheric dust counting efficiency of no less than 95%, the high efficiency air filter.
7. Clean operating room return air mouth must set a filter layer. When the system pressure to allow, should be set to 1 or more microns in atmospheric dust counting efficiency of no less than 50% of efficient filter layer, return air mouth hundred vertical adjustable blade blade should be chosen. Return air mouth can be set up carbon fiber filter if necessary.
8. The first level in the clean operating room system and save the wind filter, should be adopted to 5 microns or atmospheric dust counting efficiency of no less than 50% of the coarse filter efficiency, p 1 microns in atmospheric dust counting efficiency of no less than 50% efficient filter and the acuity 0. 5 microns atmospheric dust counting efficiency of no less than 95% of the triple filter combination of hepa filter. When necessary, can be set up separate air duct, and added a harmful gas adsorption device.
