Welders can enjoy a breath of fresh air

RESPIRATORY equipment specifically designed for welders is Speedglass claim for its Fresh-Air system.

The Fresh-Air kit is available with both gas and particle filtration and a range of different auto-darkening welding filters for eye protection.

Battery-powered electronic control of air flow to the user provides a constant air supply independent of working conditions and loading on the filter. Flow can be pre-set to 160-200 litres/min.

A built-in alarm gives warning of low battery condition or low air flow, which is often associated with the need for a filter change. Battery life is a minimum eight hours between rechargings.

Price starts from about £400, which includes the cost of the welding helmet (01823-680166).
