Simple and easy to use design

A simple design with filter, hose, charging ports, and an on/ off switch allows for easy, straightforward operation, permitting the provider to focus on patient care while knowing they are protected.

Comfortable extended wear

More comfort and flexible applications promote maximum use for extended periods, ensuring protection to providers in any circumstance.

Reduced user burden

Exceeds NIOSH airflow requirements of 170 liters per minute (lpm), reducing pulmonary stress and risk of respiratory illness. The design provides the highest levels of protection without interfering with patient care or additional strain on the healthcare provider.

Ultimate respiratory protection

Use in a two-filter, high-efficiency configuration for biological protection, or a three-cartridge combination for protection against organic vapors, acid gases, ammonia, formaldehyde, methylamine, and particulates.

Lightweight and compact blower

The comfortable, waist-mounted blower weighs 1.3 pounds, including the onboard battery, in a compact 3-inch by 5-inch square box threaded on an adjustable belt.

Advanced warning system

Two independent, audible alarms for low airflow and low battery facilitate safe and timely exits from contaminated areas.
