positive pressure supplies

1Passed ISO9001-2008 2Leading domestic level 3High quality+Best service 4Used in contaminated or oxygen-deficiet atmospheres

Self-contained positive pressure compressed oxygen breathing apparatus

Usage and Theory:

Used in the contaminated or oxygen-deficient atmosphere, such as mine, fire fighting, chemical industry, petroleum and tunnel and so on.Adopts positive pressure principle to supply oxygen, which makes the pressure in the facemask exceed the atmospheric pressure, so it can efficiently stop harmful gas outside from flowing into the facemask, which assure rescues corps safety.

Features:

Logical structure design, comfortable and reliable.Logical casing design, crush-proof, good impermeability, safe and stable.Excellent cooling performance, light and easy to carry.Adjustable constant flow unit: Users can adjust the oxygen supply constant amount according to their needs. The supply is stable, clear and long lasting.Self-supplement unit: supplement oxygen in time, safer and save more oxygen.Facemask is equipped with quality speaking unit and drainage , more convenient and user friendly.
