The LIB blowing rain test chamber is designed to simulate the harsh blowing rain environment specified in MIL-STD-810H Method 506.6, and is often used to verify the waterproof performance of high protection level products such as military, aerospace, and outdoor equipment. The LIB blowing rain test chamber replicates wind and rain conditions by precisely controlling wind speed, rainfall intensity and test angle to assess whether products can withstand extreme weather challenges.

Product details
Blowing Rain Test Chamber
Workroom Structure
Corrosion-resistant, equipped with an observation window and lighting for convenient monitoring of the testing process. Cabin size: 1m³ (Customization supported)
The thickened sealed door is equipped with an electromagnetic lock to prevent accidental opening during testing. The observation window is equipped with a wiper and defogging function.

Turntable
Simulate the exposure angles in different directions of the equipment in a rainy environment. Diameter: Ø800mm (customizable),load-bearing capacity: 50kg, speed adjustable, forward and reverse rotation programmable, supports intermittent operation.

Spray system (nozzle)
High-precision nozzles simulate natural rainfall and are distributed on the top and side walls of the test chamber, with a wide coverage and uniform spraying.

Axial flow fan (rain blowing simulation)
High-power axial flow fans are used to implement Procedure II rain-blowing test in MIL-STD-810H, simulating a strong wind mixed with rain environment. Maximum wind speed: ≥18 m/s.
