Polymer laminar film membrane filter membrane for laminar flow
room's membrane ceiling
The device used in the clean room of the pharmaceutical industry is
below the high-efficiency filter at the air outlet. The use of the
equalizing membrane is generally seen in the 10,000, 1000 and 100
clean rooms of the pharmaceutical industry when the requirements
for cleanliness are relatively high. The filtering effect of the
membrane itself is not very strong, and the dust filtering is
mainly controlled by the front high efficiency filter. The function
of the equalizing membrane is mainly embodied in the word “average
flow”, which means literally. The airflow from the high-efficiency
filter of the air outlet is evenly laminated down without turbulent
flow, so that the cleanliness can be better controlled to achieve
the effects of 10,000, 1000 and 100.
Usually its style is more rectangular, of course, this can be
customized according to the size. The outer frame material is
generally aluminum alloy and stainless steel.
1. Overview
It plays a role in the vertical passage of the airflow and changes
the turbulent flow of the original airflow. The deviation between
the point-by-point wind speed and the average wind speed can be
within ±10%.
Adopting a uniform flow film to minimize the exposure of parts,
easy to clean, beautiful and generous
2.Characteristics
Main features of the equalizing film: high light transmission,
breathable (small wind resistance), waterproof, easy to clean, acid
and alkali resistant.
Continuous stable operating temperature: no higher than 70℃
3.Technical parameters.
Aluminum bracket, specifications are 18*22mm, 15*25mm, 20*30mm,
25*38mm, 35*50mm (X type), etc., wall thickness 1.2-2.0mm.
304# stainless steel bracket, specifications are 13*25mm, 15*15mm,
