Smoke Personal Escape Gas Masks

Model Number: DSA-CO

Overview

A personal respiratory protective device with visor, hood and built-in filter for escape from fire. Protects against smoke and CO (Carbon Monoxide) inhalation. Complies with European Standard EN-403.

Features

Pocket-size
Dons within seconds. No adjustment straps
One size fits all
Strong, fire-resistant, elastic rubber hood, protects the entire head and seals comfortably at the neck
Large visor, made of flame-retardant transparent film, allows a wide field of view
High-efficiency, electrostatic particle filter, with extremely low pressure-drop to allow easy breathing
A filtration unit containing low pressure electrostatic particle filter, impregnated charcoal cloth layers to absorb toxic gases and catalyst for Carbon Monoxide Oxidation.
A unique breathing device (patent pending) enables rapid exhalation and improves the physiological conditions for the user, preventing built-up of heat or vapor inside the mask
Training model available
