RY-SAR-05 Lithium Battery Powered Long Tube Respirator for One Person

Product Overview

The RY-SAR-05 is a single-person electric long-tube respirator that runs on a rechargeable lithium battery pack instead of a mains cable. The stainless steel blower housing carries a red and a green push button, a rocker switch, an inline fuse holder and a digital display showing battery capacity and voltage, with hose ports on its lower face. The set is supplied with a coiled corrugated hose with quick-fit metal couplings, a full-face mask with a yellow frame, an orange and black striped waist strap, a battery charger and the manual. It is the version to specify where there is no safe place to plug in — inside a bund, on a tank roof, at a temporary works point or on a jetty — and where a trailing cable would be a trip or a spark risk in itself.

Why Battery Power Changes the Risk Picture

Cutting the cable removes two problems and introduces a third.

What it removes. A mains lead across a walkway is a trip hazard for the wearer and everyone else, and a lead in a classified area is a cable to be protected, routed and inspected. Battery power removes both: the blower can be set down where the work is, with no cable to route and no plug to find.

What it introduces: a runtime that ends. The blower now stops for one reason only that matters — the pack is flat. That moment must never arrive while someone is inside, so the digital capacity display is the most important instrument on this set: it must be read before entry, not during. Cold weather cuts usable capacity, an ageing pack loses capacity silently, and a pack that was "fine last week" can fail on the day. The practical regime is a charged spare at the entry, a recorded check of the display before each entry, and a rule that any low-battery indication means the wearer leaves immediately rather than finishing the task.

Charging is not covered by the explosion-proof rating. The blower housing is built for classified areas; a charger plugged in and a pack on charge are not. Batteries must be charged in a safe, ventilated, non-hazardous area with the correct charger, never inside the zone and never improvised from a vehicle socket. A pack that has been dropped, swollen or wetted should be taken out of service rather than recharged.

The spare port matters. The housing carries two hose ports so that the same body can serve one or two wearers. On a single-person set only one port is used, and the unused port must be plugged: an open port bleeds airflow and quietly reduces what reaches the mask. If the cap is missing, the flow check at the mask will show it.

The constants do not change with the power source: the blower moves ambient air rather than making it, so the intake must stand in clean air, upwind and outside the zone; and there is no escape cylinder, so any interruption — flat battery included — means leaving at once.

Key Features

• Rechargeable lithium battery pack, so the set runs without a mains cable and without a plug in the work area.

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

• Red and green push buttons plus a rocker switch, with an inline fuse holder on the front face.

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

• Two hose ports on the housing, so the same body serves single or twin configurations; the unused port must be plugged on a single-person set.

• Coiled corrugated breathing hose with quick-fit metal couplings at both ends.

• Full-face mask with a yellow frame, wide visor and exhalation valve.

• Orange and black striped waist strap with rings, carrying hose weight off the facepiece and staying visible in low light.

• Charger and manual supplied with the set; no fuel, no cylinder and no compressed air line required.

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 before entry and record the reading; fit a freshly charged pack rather than relying on the previous shift's charge.

3. Plug the unused hose port, run the hose on a supported route with no sharp bends or door traps, and connect the mask coupling until it clicks.

4. Fit the mask, carry out a fit check, and confirm airflow at the mask before the wearer puts it on — a plugged port and a charged pack both show up here.

5. Appoint a standby person at the blower who holds the spare pack, watches the display and can act on a low-battery indication.

6. Brief the evacuation signal and make it a rule that any interruption, including a flat pack, means leaving immediately rather than finishing the task.

Battery and Charging Management

Before each use: read the capacity display, inspect the pack casing for swelling, cracks or wet ingress, and check the contacts and the fuse holder.

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

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

Pack life: rotate packs, record their age, and retire any pack whose runtime has fallen noticeably; a pack that no longer holds a shift's work is a failed component, not a spare.

Annually: replace the mask gasket and exhalation valve, check the hose couplings, and review the battery stock against the 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. The mask must be fit tested to its wearer. The explosion-proof rating covers the blower housing in its intended zone; it does not cover charging, so batteries must be charged outside the hazardous area. Loss of battery power is a loss of protection, and the site's procedure must treat it as an evacuation trigger. Local rules on confined-space entry, permit-to-work and standby arrangements apply on top of the equipment.

Applications

Work inside bunds, on tank roofs and at temporary points with no safe power outlet, jetty and dock work, painting and coating in classified areas, and any task where a mains lead would itself be a hazard.

Ordering

State the model RY-SAR-05, the hose length, the number of battery packs required for the shift pattern, the mask size, and the zone classification where the blower will stand. Confirm whether a spare pack, an additional charger or a second mask is to be included, and state the language required for the manual. Ask for the runtime figure for the pack against the hose length you intend to use, so the shift plan can be built around it rather than discovered on site.
