Features of VOC release chamber
♦ The wind speed adjustment inverter is installed at the rear of the box, with a recessed design, which is easy to protect;
♦ The diameter of the air outlet of the air plate is reduced, and the diameter is about 2-3mm, so as to avoid the formation of flowing air and raise the dust in the laboratory;
♦ The heat dissipation holes at the bottom of the front are changed into a louver-like shape, the internal compressor cannot be seen from the outside, and dust can be prevented from falling into;
♦ There is an isolation layer between electrical loads to avoid mutual interference;
♦ The box body and the box door are filled with filling materials to ensure the slightest opening and closing sound of the box door.
♦ The door handle has excellent mechanical properties;
♦ There are 3 sampling holes, and the connection between the inner and outer diameters is flanged to ensure sealing;
♦ The caster support triangular plate is thickened by 5mm to ensure the long-term durability of the box;
♦ The air outlet holes of the internal circulation fan blades are not convex, and the air ring is inlaid inside to ensure the overall appearance of the box;
♦ The box door adopts double sealing strips to ensure that the inner compartment is sealed and there is no air leakage;
♦ The position of the internal fan is adjusted accurately to ensure the accuracy of the test;
♦ The appearance color of the equipment adopts computer white, which is beautiful and has a sense of the times.
