Full hood with TCA plastic visor
(suitable for protection from splashes and impact from light, low velocity particulate matter, such as dust, grit and fibre)
The light-weight hood is designed to fit with the Tornado, Power Assisted Air Purifying Respirator, (PAAPR) one of the most versatile such devices made.
Air is routed, at high volume (>140 litres/minute), from either the fan assisted filter unit, or from a compatible air-line belt manifold that is fed from a reduced pressure, compressed air source (compliant with the requirements of BS 4275). The air-feed manifold directs air from the crown, down over the visor, thus avoiding uncomfortable drafts to the face and assisting in maintaining directional flow towards the neck-seal and exhaust port, pictured.
This hood provides cool comfort, in most, working environments and Assigned Protection Factors of up to 40. Fit-testing is unnecessary and integral respiratory safety is dependent on the airflow, contained by the hood, constantly venting outward, through exhalation valves, or a closely fitted neck cape, or seal.
If used with air-lines, for air supply, the high flow-rates consumed will make this (LDH3) type of use very uneconomical for compressed air costs and it might be better to consider a demand valve operated, air-supplied mask, considering the additional use of an over-hood, to augment protection for the head and shoulders, against splashes, aerosol and dust contamination.
Be aware that most such devices are nowhere near so robust as Self Contained Breathing Apparatus and related umbilical (air supplied) systems but, in a controlled environment, such as is represented in most workshops where processes involving powders, dusts, dye-stuffs, lacquers and paint-sprays exist, they are quite adequate - and, of course, much cheaper to buy.
Tested to EN 12941 class TH3 for Powered respirators and to EN 1835 class LDH3 for Arline respirators.
