Pratt gravity fed portable eyewash unit, 35L

The SE5000 is a 35L portable eyewash station from Pratt, built for sites where you cannot run a plumbed water supply to the spot that needs eye-flushing. It is gravity fed, so it works off the head of water in the tank rather than mains pressure. That makes it a sensible choice for remote work areas, temporary setups, or any bay where a permanent fixture is not practical.

The unit holds 35 litres and is made from polyethylene, so it is light enough to move and resistant to the kind of knocks a portable unit cops on site. It ships with one bottle of SE4764 water preservative, which keeps the standing water usable between refills. Pratt lists the station against AS4775 and ANSI Z358.1, the two standards most Australian buyers look for when specifying emergency eyewash equipment.

Working out if a portable gravity-fed unit suits your site

The first question is whether you can plumb water to where you need it. If you can, a fixed plumbed station is usually the simpler long-term answer. If you cannot, a portable gravity-fed unit like this one becomes the practical option. The 35L size suits a single work point or a small team. If you expect to cover a larger area or more people, step up to a higher-capacity unit so the available flush volume matches the risk.

Think about where the unit will live. The 560 x 250 x 360 mm footprint is small enough to sit on a bench, a stand, or a dedicated shelf near the hazard. Position it so anyone working with chemicals can reach it quickly without hunting for it, since the value of an eyewash is in how fast someone can get to it after a splash.

Setting up and filling

Fill the tank with clean potable water and add the supplied SE4764 water preservative. The preservative is there to keep the stored water in usable condition between changes, which matters for a self-contained unit that is not being constantly refreshed by mains flow. Make sure the unit sits level and the nozzles are clear before you sign it off as ready.

Inspection and water changes

Standing water needs a routine. Set a schedule to check the fill level, change the water, and top up the preservative so the station is always ready to use. Keep the nozzles clean and free of dust. Confirm the inspection and water-change intervals against the product documentation and your own site procedures, and check that the unit's compliance with AS4775 and ANSI Z358.1 still meets what your workplace has specified.

All four units here are emergency eyewash or shower products from Pratt, so this is a same-type comparison. The real differences come down to capacity, how the unit is supplied with water, and whether it is portable or a fixed fitting.

If your only constraint is that you cannot run plumbed water, the choice is mostly about size and what you need to flush. The SE5000 covers a single point well, and the SE5050 is the same idea with 55L on hand when you want more flush volume or have more people to cover. The SE590A moves up to eye, face and body washing with a drench hose, and it uses a compressed-air pressurised tank rather than gravity, so it suits splashes that go beyond the eyes.

The SE546 is the odd one out here: it is a fixed pedestal unit that needs a plumbed supply, and it is built for eye hazards rather than full face or body flushing. Pick it only when you have water at the location and want a permanent fitting rather than a unit you can pick up and move.

For a site that cannot run plumbed water to the hazard, this Pratt unit does the core job in a straightforward way. The gravity-fed design keeps it simple, the polyethylene body is practical for something that gets moved around, and including the SE4764 preservative means you can fill it and keep the water usable from day one. The 35L size is honest about what it is: a single-point station rather than a unit meant to flush a whole crew.

What is confirmed on the listing is the capacity, the portable gravity-fed format, the polyethylene construction, the dimensions, the included preservative, and the AS4775 and ANSI Z358.1 listing. Those are the facts to lean on when you specify it.

What you should verify on the product page or datasheet before you commit: nozzle detail, flush duration at 35L for your situation, the recommended water-change and inspection schedule, and that the listed standards match exactly what your workplace requires. If you need more flush volume or face and body coverage, look at the larger or pressurised units in the same Pratt range rather than stretching this one past what it is built for.
