RY-SAR-06 Lithium Battery Powered Long Tube Respirator for Two Persons

Product Overview

The RY-SAR-06 is a two-person electric long-tube respirator running on a rechargeable lithium battery pack, with no mains cable to the blower. The stainless steel housing carries a red and a green push button, a rocker switch, an inline fuse and a digital display showing battery capacity and voltage, with two hose ports on its lower face. The set is supplied with two coiled corrugated hoses with quick-fit metal couplings, two full-face masks with yellow frames, two orange and black striped waist straps, a charger and the manual. It is specified where two people have to work inside a classified area and there is no safe place to plug in — a bund, a tank roof, a jetty or a temporary work point — so the cable that would otherwise be a trip and a spark risk is removed.

Two Wearers on One Battery: Where the Margins Go

Battery power and a second wearer each remove a margin, and on this set they are removed together. That combination is what the buyer has to think about.

The pack feeds two blowers' worth of demand. Two masks drawing from one housing move more air than one, so the same pack that gives a single wearer a comfortable shift gives two wearers a shorter one. The runtime figure has to be quoted for two masks on the hose length actually used, not for one mask on a short hose, and the shift plan has to be built around that number.

A flat pack strands both people. A cable can be re-routed and a plug can be found; a battery that reaches the end of its charge cannot. When it goes, both wearers lose protection at the same moment, in the same place, with two hoses to bring out. That means the standby resource at the blower has to be able to bring two people out, and there has to be a charged spare on site — not in the stores, at the entry.

The display is a two-person instrument. The reading relates to both wearers, so it must be read and recorded before either enters, and watched during the work by the standby person. A single wearer can glance at it themselves; with two inside, nobody is watching it unless someone is appointed to.

Two hoses, two shares. Both ports are in use, so there is no plugged port to worry about — but the shares still depend on hose length. Unequal lengths give the shorter run more air, and the wearer on the longer hose is the one who will feel it last and say it latest.

Charging stays outside the rating. The housing is built for the zone; the charger and a pack on charge are not. Charging happens in a safe, ventilated, non-hazardous area with the supplied charger, never inside the zone, and a dropped, swollen or wetted pack is taken out of service rather than recharged.

The constants hold: the blower moves ambient air rather than making it, so the intake must stand in clean air, upwind and outside the zone; and neither wearer has an escape cylinder, so any interruption — including a flat pack — means both leave immediately.

Key Features

• Rechargeable lithium battery pack, so the set runs without a mains cable anywhere near the work.

• Digital display showing battery capacity and voltage, readable at the blower before entry and during the shift.

• Two hose ports on the housing, both used on this set, feeding two wearers from one blower.

• Red and green push buttons, rocker switch and inline fuse on the front face.

• Stainless steel housing with carry handle, resistant to wash-down and to most process atmospheres.

• Two coiled corrugated hoses with quick-fit metal couplings at both ends.

• Two full-face masks with yellow frames, wide visors and exhalation valves; sizes per wearer.

• Two orange and black striped waist straps with rings, carrying hose weight off the facepieces and staying visible in low light.

• Charger and manual supplied; no fuel, no cylinder and no compressed air line needed.

Technical Specifications

Deployment and Use

1. Site the blower in clean air, upwind of the work and outside the zone, with the intake clear of exhausts, vents and dust.

2. Read the battery display with both masks connected, record the reading, and fit a freshly charged pack rather than finishing the previous shift's charge.

3. Run the two hoses on separate supported routes with no shared crossing at the entry, and keep a charged spare pack at the blower.

4. Fit each mask to its own wearer, fit check both, and confirm airflow at each mask before either person enters.

5. Appoint a standby person whose job includes watching the display, holding the spare pack and bringing both wearers out if it drops.

6. Brief the evacuation signal and make it a rule that both leave on any interruption, including a low battery indication.

Battery and Charging Management

Before each use: read the capacity display with both masks connected, inspect the pack for swelling, cracks or wet ingress, and check the contacts and the fuse.

After each use: remove the pack, clean and dry the housing, and charge the pack in a safe area so the next shift starts full.

Charging discipline: charge only in a non-hazardous, ventilated area with the supplied charger; never inside the zone, never a damaged pack, never unattended overnight in a work area.

Pack life: rotate packs, record their age, and retire any pack whose runtime no longer covers the two-person shift; a pack that has lost a third of its runtime is a liability on a two-wearer set, not a spare.

Annually: replace both mask gaskets and exhalation valves, check hose couplings, and review battery stock against the actual work pattern.

Standards and Compliance

This is a supplied-air respirator: it does not generate oxygen and must not be used in an oxygen-deficient or immediately dangerous to life or health atmosphere unless the intake air is guaranteed clean and the assessment says so in writing, and it must never replace self-contained apparatus where an escape supply is required. Each mask must be fit tested to its own wearer and must not be shared without cleaning and disinfecting. The explosion-proof rating covers the blower housing in its intended zone; it does not cover charging, so packs must be charged outside the hazardous area. Loss of battery power is a loss of protection for both wearers and must be written into the site's procedure as an evacuation trigger. Local rules on confined-space entry, permit-to-work and standby arrangements apply on top of the equipment.

Applications

Two-man work inside bunds and on tank roofs with no safe outlet, jetty and dock operations, pair inspection of pits and sumps, coating and solvent work in classified areas, and any task where a mains lead would itself be a hazard and two people must stay protected together.

Ordering

State the model RY-SAR-06, the length of each hose, the number of battery packs required for the shift pattern, the supply voltage for the charger, and the mask size for each wearer. Confirm whether a spare pack, an additional charger or spare masks are to be included, and state the language required for the manual. Ask for the runtime figure with both masks running on your hose lengths, so the shift plan can be built around it rather than discovered on site.
