Optrel swiss air PAPR Back-Worn Powered Air Respirator
Description
Back-worn PAPR for dust, particles and gas filtering with masks
The Optrel swiss air is a powered air-purifying respirator worn on the back with a harness, supplying filtered air to an approved Optrel mask. Because the blower, battery and harness sit on the torso, the head carries only the mask and a light air hose, which makes the system practical for long shifts in grinding, cutting, painting preparation and similar dusty tasks. With a combined ABE1 filter, protection against certain gases is added to particle protection.
The manual describes an electronic flow control that maintains an air flow of at least 100 L/min, three selectable flow levels, automatic temperature and altitude compensation when the control panel is connected, and acoustic and visual alarms for low battery, clogged or missing filter and low air flow.

Using swiss air safely
The manual requires that the mask is undamaged and a hose and filter check is made before every use. When working with flying sparks or spatter, the mask and face must be protected additionally, for example with a clearmaxx for grinding or an Optrel welding helmet for welding. The battery must not be charged or disconnected in potentially explosive areas, and annual maintenance by a specialist company qualified by Optrel is called for in the document.
What to confirm before ordering
Confirm the required protection class (particles only, or particles plus gases with ABE1), the mask size and variant, whether the control panel is needed and the spare battery count. For a welder who needs PAPR protection under a welding helmet, see the
belt-worn blower instead. Related equipment is listed under Respiratory Protection.Documents and quotation
The attached document is the Optrel swiss air user manual (multilingual, English pages included) with the technical information table, scope of delivery and safety notes. State the variant, mask type and quantity with your quotation request.

About brand
Welders usually know Optrel by the view through the lens. The Swiss company, founded in 1986 and based in Wattwil, makes auto-darkening welding helmets, grinding helmets and powered air respirators. Seven Star LLC lists the Optrel crystal2.0, e684, panoramaxx clt and panoramaxx 2.5 helmets and supplies them, with their spare lenses and headgear, to fabricators and contractors in Oman and the GCC.
Optrel welding helmets listed here
The crystal2.0 and the panoramaxx clt use Optrel's Crystal Lens Technology, which gives a very light, clear view at shade level 2.0 before the arc strikes. The panoramaxx helmets have a nose cut-out that brings the lens closer to the eyes and widens the field of view; the panoramaxx 2.5 has a light state of shade level 2.5. The e684 adjusts its shade level automatically to the arc. For fume protection Optrel pairs helmets with its e3000X and swiss air respiratory systems.
Where Optrel helmets are used
Fabrication shops, pipe spools, tank and structural work and site maintenance, on TIG, MIG/MAG and stick welding.
Ordering Optrel helmets and spares: what we need
State the helmet model and color, with or without respirator connection, and any hard hat adapter. For spares, give the model and say front cover lens, inside cover lens, sweatband or headgear.
