The SpringFit™ Range. Available in FFP3 and FFP2 valved and unvalved, with a nuisance odour carbon layer available on the FFP3 model. Typhoon™ Valve. The Unique Typhoon™ valve has been designed to reduce breathing resistance, heat and moisture build-up. The valve is unaffected by any moisture, and therefore can be used with the same performance under very low temperatures. Compact. The fold flat design makes SpringFit™ more compact, and easily pocketed. SpringFit™ is also individually packed to ensure a high level of hygiene. This mask provides protection against welding fumes.
