Purpose
Dust (< 150 µm) procedure. This test is performed to help evaluate the ability of materiel to resist the effects of dust that may obstruct openings, penetrate into cracks, crevices, bearings, and joints, and to evaluate the effectiveness of filters
Standard
MIL-STD-810G.
Design principles
Its structure is a funnel,a collecting hole for dust on the bottom,on the right side of this hole is equipped with a suction inlet of turbine circulating fan.Send the pumped dust into the bottom of inner chamber and then to the left side and go upwards;blow the dust into test chamber from the left side; the dust should be blown rightwards in a horizontal direction and then begin circulation
Material
1. Material: SUS304 stainless steel plate
3. Chamber door with a large observation window
4. Unique duct design, to ensure the concentration of laminar flow laminar flow
5. Basic structure: Pre-treatment box, test chamber, vacuum port, dust box, circulating dust device, vacuum system, dust tank, flow valve, heating system, backflow vane, sample carousel, screen, concentration meter And so on.
