PAPR system

According to Parweld, the system offers a portable, lightweight and battery powered belt mounted solution to the respiratory hazards created during the welding process. It filters out contaminated air allowing clean purified air to be supplied to the head unit using high efficiency replaceable particulate filters. 
The air stream combined with the positive pressure created within the helmet prevents contaminated air entering the breathing zone.

The platform incorporates features such as an adjustable air flow ranging from 150 to 220 lpm. Eight different settings allow the user to adjust the unit to their specific environment and comfort level.

The unit is powered by smart replaceable li-on batteries providing operating times of six to eight hours (flow rate dependant) and a charge cycle of three to four hours. The unit incorporates a two stage filter process, the main P3 filter gives the required essential protection against welding particles, smoke and dust providing the user with a protection factor of 20. The standard P3 filter can be complimented with a wrap-around pre filter which removes large dust particles and so extends the life of the main filter.

The Air Respiratory System includes a three alarm warning system if the flow rate falls below the required minimum level to ensure that the user’s protection is not compromised. The fan speed automatically increases to compensate any drop in the flow rate. If this cannot be maintained the audible alarm will sound and the LEDs flash to enable the user to safely leave the area. If this is not acted on the unit will vibrate and increase the alarm volume.

The Parweld PAPR (XR926A) unit conforms to BE EN 12941 TH2P R SL.
