Sundstrom SR 500 fan unit

The Sundstrom SR 500 fan filter unit is an efficient and easy-to-use battery-powered filter unit that allows comfortable work in conditions requiring the use of respiratory protection. The forced air circulation system reduces user fatigue due to breathing resistance that occurs when using a standard protective mask, in which the air flow is caused by the force of the lungs. Forced air flow is particularly useful during long-term work in difficult conditions and high temperatures.

• operation devices, battery indicators are clearly visible, available at your fingertips.
