RY-EA-BW2 Yellow ABS Eyewash Bowl with Integral Perforated Drain Strainer

RY-EA-BW2 Yellow ABS Eyewash Bowl with Integral Perforated Drain Strainer

Product Overview

The RY-EA-BW2 is a yellow eyewash bowl moulded in ABS, with a central drain outlet surrounded by a ring of small perforations formed in the moulding itself — that is, the strainer is part of the bowl, not a separate disc. The basin is round and shallow with a raised central boss, and it fixes to the station bracket through the existing mounting. It is the plastic counterpart to a stainless bowl, supplied as a spare for ABS-bowl stations and for sites that prefer a non-corroding, high-visibility basin.

What the Moulded Strainer Gives and Costs

Forming the strainer into the bowl is a neat piece of design: there is no separate disc to lose, no disc to fall down the drain, and nothing that a user can push through into the waterway. On a station where the small parts of a head keep going missing, that is a real advantage.

It also creates the bowl's characteristic failure. Those perforations are the only path from the basin to the drain, and they are small, moulded, and not removable. Hair, lint, scale and the residue of whatever was being washed collect in them, and when a few are blocked the bowl starts to hold water and then to overflow at the rim during a flush — with the user bent over it. Cleaning is by flushing and poking through from the moulded face, which is slower than lifting out a disc and is the job that inspection sheets most often skip.

The second weak point is the drain boss. The drain fitting screws into the raised centre, and the boss is where the moulding is stiffest and most highly stressed: over-tightening the fitting, or dropping the bowl on its base, cracks it there. A crack at the boss leaks under the bowl and looks like a failed drain washer.

The material carries the usual ABS trade-offs. It does not corrode, it is light on a thin bracket, and yellow reads as emergency equipment from across a room. It is also temperature-limited — tepid water is fine, but a hot flush from a failed mixing valve can soften and distort the bowl — and it degrades under sustained UV, going chalky and brittle on an outdoor station. For a sheltered indoor bench on a controlled tepid supply it is a sensible, cheap, serviceable part; for an external station, stainless is the better buy.

Key Features

• Yellow ABS bowl, high visibility against stainless and against workshop finishes.

• Integral perforated strainer moulded around the drain, so no separate disc can be lost or pushed through.

• Raised central drain boss that directs water to the outlet rather than letting it pool at the rim.

• Round shallow basin profile that limits splash at the rim during a flush.

• Non-corroding material, so standing water between tests leaves no rust stain in the basin.

• Light weight that does not load a plastic bracket or a thin bench top.

• Bowl only, so an existing spray head, drain fitting and bracket can be reused.

• Replacement part for bowls that are cracked at the boss, hold water, or have gone brittle.

• Individual packing, so the moulded face arrives without scuffs.

Technical Specifications

Fitting

1. Isolate the station supply, lock the valve off, and remove the spray head and the drain connection before releasing the bowl.

2. Compare the new bowl with the old one for diameter, drain position and mounting pattern; a bowl that is close in size but wrong in pattern will not seat or seal.

3. Fit the drain fitting with a fresh washer and tighten to the boss by hand plus a part turn — the moulded boss cracks under a wrench.

4. Refit the spray head through the bowl and confirm the head does not rotate with the nozzles.

5. Restore the supply slowly, run the station at full flow and confirm the perforations pass the water without the bowl backing up.

6. Re-check the nozzle height above the floor and the distance from the wall, then record the flow reading with the caps open.

Maintenance and Inspection

Weekly: operate the eyewash for at least three minutes and confirm the bowl empties through the perforations, leaving no standing water.

Monthly: flush the basin and work through the perforation ring from the moulded face to clear hair, lint and scale; check the boss ring for hairline cracks.

Quarterly: check the drain joint for weeping, inspect the bowl underside for cracking or discolouration, and confirm the bowl is not deformed by heat.

Annually: replace the bowl if the perforations cannot be cleared, the boss is cracked, or the moulding has gone chalky and brittle.

Standards and Compliance

The bowl is a component of an emergency eyewash; the installed station must meet ANSI Z358.1-2014 in full — fifteen minutes of flushing with tepid water at 20–37 °C, hands-free activation, nozzles at the required height above the floor and clearance from the wall, and unobstructed access within ten seconds of the hazard. A bowl that holds water or overflows at working flow is a defect even when the nozzle flow is correct, because the user cannot hold position in it. Replacement of a bowl does not by itself make a station compliant, and the height and clearance must be re-verified after fitting. Tepid water also protects the part: flushing above the tepid band risks distorting a moulded bowl.

Applications

Replacement of cracked, distorted or discoloured bowls on ABS-bowl eye wash stations in laboratories, indoor benches and workshops; stations where a separate strainer disc has repeatedly been lost or pushed through; and spare-part stock for maintenance teams.

Ordering

State the model RY-EA-BW2, the drain outlet size, and the make and model of the station it is to fit so the mounting pattern and the spray head thread can be checked. Confirm whether a drain fitting and washer are to be supplied with the bowl. If the station is outdoors, exposed to frost and sun, or periodically flushed hot, specify the stainless bowl instead — the ABS moulding is the right part for an indoor tepid-water station and the wrong one for those conditions.
