RY-SAR-02 Explosion-Proof Electric Long Tube Respirator for Two Persons with Twin Hose Outlets

Product Overview

The RY-SAR-02 is a two-person electric long-tube respirator: one stainless steel blower housing with an explosion-proof motor delivers ambient air through two outlets to two long corrugated hoses, each ending in a full-face mask with a yellow frame and its own waist strap. The set is supplied with the explosion-proof certificate, test report and manual. It is the configuration to choose where two people work as a pair inside the same area — vessel entry with an attendant inside, two-man inspection of a tank or pit, or coating work where a second person is spraying alongside the first — because it removes the second blower from the site and gives both wearers the same air source and the same start-up check.

What "Two Persons" Changes

Sharing one blower is convenient, but it alters four things that a single-person set does not have to think about.

The flow is now shared. Two masks draw from one blower. The unit has to be sized for both masks running together, not for one at a time, and the two hose lengths should be comparable: with unequal lengths the shorter path takes the larger share, and the wearer on the long hose quietly gets less air. If the work needs unequal lengths, check the flow at the far mask before entry rather than assuming.

The failure is now shared. If the blower stops, the power is lost or the intake is engulfed, both wearers lose protection at the same moment. That doubles the rescue load: two people have to be brought out, not one, and the standby arrangements at the blower must be able to do it. A single attendant who was adequate for one wearer is often not adequate for two.

The hoses now interfere with each other. Two long hoses in the same vessel tangle, cross, and pull on each other's masks. Each wearer needs a separate route out, and the pair needs an agreed rule on which side of the work each keeps to.

The masks are personal. A full-face mask is fitted to a face and must not be passed between wearers without cleaning and disinfecting, and each wearer needs the correct size and a fit check every time. Two masks in one kit are not interchangeable spares for a badly fitting one.

And the two constants of every long-tube set: the blower does not make air — it moves ambient air, so its intake must stand in clean air, upwind, outside the zone — and there is no escape cylinder, so any interruption means leaving rather than waiting to see whether the supply recovers.

Key Features

• Single explosion-proof blower feeding two masks through twin hose outlets, so one power feed and one start-up check serve both wearers.

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

• Two long corrugated breathing hoses with quick-fit couplings, coiled for transport.

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

• Two waist straps, one per wearer, carrying hose weight off the facepieces.

• Explosion-proof certificate, test report and manual supplied with each set.

• Mains-powered with a plug and cable; no cylinders to change and no charging routine between shifts.

• Suits pair working where an attendant and an entrant, or two operatives, must stay protected at the same time.

• Compact kit that one person can carry and set up, with both hoses deployed from a single point.

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 vehicle exhaust, vents and dust.

2. Confirm the nameplate gas group and temperature class match the zone where the blower stands, and keep the certificate with the set.

3. Run the two hoses on separate routes, supported or overhead, with no shared crossing point where one can pull the other's mask.

4. Fit each mask to its own wearer, carry out a fit check, and confirm both wearers breathe comfortably before either enters.

5. Check the flow at the far mask with both running — not one at a time — and record the result if the two hoses differ in length.

6. Brief the two-person evacuation route and appoint enough standby resource at the blower to bring both wearers out, then record the entry on the permit.

Maintenance

Before each use: inspect both hoses for cracks, flattening and damaged couplings; check both masks, gaskets and exhalation valves; run the blower and confirm airflow at both masks.

After each use: clean and disinfect each mask separately, wipe and coil the hoses without sharp bends, and check the cable and plug.

Monthly: inspect the intake and fan for dust, check the earth continuity and cable gland, and confirm both outlets and couplings are sound.

Annually: have the explosion-proof enclosure and motor inspected by a competent person, replace both mask gaskets and exhalation valves, and re-check the certificate against the zone if the process has changed.

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 masks must not be shared without cleaning and disinfecting. The blower, hoses and masks are assessed as one system; a certified blower with unmatched masks is not a certified respirator, and twin outlets must be shown to deliver adequate flow to both wearers simultaneously. Local rules on confined-space entry, permit-to-work and standby arrangements apply on top of the equipment, and the certificate supplied with the set must be kept with the unit and produced at inspection.

Applications

Two-man vessel and tank entry where the blower can stand in clean air, pair inspection of pits and sumps, spray coating with two operatives, solvent and chemical handling in classified areas, and any task where an attendant must stay protected alongside the entrant.

Ordering

State the model RY-SAR-02, the length of each hose, the supply voltage and phase, the zone classification and required gas group and temperature class, and the mask sizes needed — two wearers rarely take the same size. Confirm whether spare hoses, additional masks or a hose reel are to be included, and state the language required for the manual. Ask for copies of the explosion-proof certificate and test report in advance if they are needed for a permit submission.
