Independent boom or bracket should be used, clean laminar flow hood installation of the level of deviation should be 1 ‰.
Laminar flow hood is one of the equipment that can shield and isolate the operator from the product. Air is drawn from the clean room and then filtered through HEPA using a fan mounted in the top pressurized compartment Vertically through the operating area, providing ISO 5 (Class 100) unidirectional flow air to critical areas. Exhaust air is exhausted from below and returned to the cleanroom area.
Clean Laminar Flow Hood Precautions
1. Check to see if the laminar flow hood surface can be cleaned, if there is any dust, you should remove the dust first.
2, the use of laminar flow hood before the use of disinfectant scrub laminar flow hood positive appearance and around.
3, the fan voltage adjustment knob to "zero" position, check whether the fuse is intact.
4, press the power switch, gradually rotate the adjusting knob, increase the voltage, the laminar flow hood began to send air using the wind speed measurement straight laminar flow wind speed. Gradually increase the voltage, to the straight laminar wind speed of 0.35m / s above that is obtained.
5, after the end, the voltage should be adjusted knob back to "zero" position, and then turn off the power switch.
