RY-SAR-08 Lithium Battery Powered Long Tube Respirator for Four Persons

Product Overview

The RY-SAR-08 is a four-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, and supplies four coiled corrugated hoses with quick-fit metal couplings, four full-face masks with yellow frames and four orange and black striped waist straps. A charger and the manual are included. It is the largest battery-powered set in this range and is used where a coating gang, a lining crew or an inspection team has to work inside one large classified volume from a single access point, with no safe place to plug in.

Four Masks on One Pack: When the Battery Becomes the Limit

On a single wearer, the battery is a convenience. On four, it becomes the element that governs the whole job, and that shift in the centre of gravity is the thing to understand before specifying this set.

The pack now carries four wearers' demand. Four masks drawing from one housing move substantially more air than one, so the runtime that covers a single wearer for a shift covers four for a small fraction of it. Even the printed runtime figure should be treated as a starting point: cold weather reduces usable capacity, pack age reduces it silently, and the four masks are running for the whole time. Plan the work in blocks with a pack change between them, rather than assuming a shift-length deployment.

When it goes, four people are stranded. A cable can be re-routed and a plug can be replaced; a flat pack stops the blower, and it does so for all four at once. Bringing four wearers out with four hoses trailing is a team rescue. If the site cannot put a rescue party at that access point, four masks on one battery is the wrong architecture and two smaller sets are the safer buy — one failure then strands two, not four.

Four hoses need a distribution point. The housing in the photographs shows two outlets on the front face, so a four-hose set has to distribute through a manifold or through additional connections that are a build detail. That arrangement should be confirmed on the drawing and asked about at the quotation stage rather than assumed; and however it is arranged, the shares depend on hose length, with the shortest run taking the most air and the longest run starved.

Somebody has to watch the display. The reading covers all four wearers and nobody inside can see it. A standby person at the blower, with the spare pack in hand and the exit route in view, is part of the equipment in practice even though it is not in the box.

Charging is outside the rating. The housing is built for the zone; the charger and a pack on charge are not. Charge in a safe, ventilated, non-hazardous area with the supplied charger, and take a dropped, swollen or wetted pack out of service rather than recharging it.

The constants hold at any headcount: the blower moves ambient air rather than making it, so the intake must stand in clean air, upwind and outside the zone; and none of the four has an escape cylinder, so any interruption means all four leave at once.

Key Features

• Rechargeable lithium battery pack, so no mains cable runs to the work position.

• Digital display showing battery capacity and voltage, read before entry and watched by the standby person.

• Four coiled corrugated hoses with quick-fit metal couplings, fed from one blower housing.

• 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.

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

• Four 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 required.

• One guarded intake for the whole crew, rather than four intakes to control around the site.

Technical Specifications

Deployment and Use

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

2. Read the battery display with all four masks connected, record it on the permit, and fit a freshly charged pack.

3. Lay the four hoses on separate supported routes with no shared crossing at the entry, and appoint one person to manage the bundle.

4. Fit each mask to its own wearer and fit check all four before anyone enters; confirm airflow at the farthest mask with all four running.

5. Keep a charged spare pack at the blower and confirm the rescue party on site can bring four wearers out before the first entry.

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

Battery and Charging Management

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

After each use: remove the pack, clean and dry the housing, and charge in a safe area so the next block 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 a four-person block; with four wearers on one pack there is no room for a tired battery.

Annually: replace all mask gaskets and exhalation valves, check hose couplings and the manifold connections, 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 all four wearers and must be written into the site's procedure as an evacuation trigger. Local rules on confined-space entry, permit-to-work, maximum entrants and standby arrangements apply on top of the equipment.

Applications

Coating and lining gangs working large tanks from one access point, four-person inspection crews, work inside bunds and on tank roofs with no safe outlet, jetty and dock operations, and classified-area solvent work where a mains lead would itself be a hazard.

Ordering

State the model RY-SAR-08, the length of each hose, the number of battery packs required for the shift pattern, the charger supply voltage, and the mask size for each wearer. Confirm the outlet and manifold arrangement for four hoses on the drawing, and confirm whether spare packs, an additional charger or spare masks are to be included. Ask for the runtime with four masks running on your hose lengths, so the work can be planned in blocks — and confirm the site's rescue plan covers four wearers before choosing this set over two smaller units.
