How does JSP PowerCap Infinity work?

JSP’s PowerCap Infinity is built around the EVO5 Olympus industrial safety helmet (certified EN 397), fitted with a Twin-Turbo blower unit. The blower draws in ambient air and passes it through TH3P-class filters before delivering roughly 160 litres per minute of filtered air into the helmet — creating a constant flow of clean air around the wearer’s head and face, which is what gives a PAPR its protection factor rather than relying on a facial seal.

The system is rated EN 12941:1998+A2:2008 class TH3 (nominal protection factor 500, UK APF 40) — the highest loose-fitting PAPR class under that standard — and pairs the blower with a panoramic EN 166 impact visor for eye protection. Power comes from an 8-hour Li-ion PowerBox2 battery.

This makes PowerCap Infinity a step up from JSP’s entry-level PowerCap Active line, which uses a different bump-cap-style headtop (EN 812 A1+ shell) and a lower EN 12941 TH1P rating with its own PowerBox1 battery — the two use entirely separate spare-parts numbering and are not interchangeable.

Always confirm the approval class marked on your own unit’s label against EN 12941 before relying on it for a given hazard level.
