Choosing a commercial pass-through dishwasher
Pass-through dishwashers load from one side and unload from the other — staff place dirty racks in, pull clean racks out, without turning around. This suits large-volume kitchens (60–120 racks/hr) where a continuous dish-flow layout is critical. Hood-type units are the entry-level pass-through format; tank-style conveyor/rack-belt units handle the highest volumes. Key specs: cycle time (60–120 seconds), rack size (500×500 mm standard), built-in vs external booster heater, and rinse-aid dosing system. See our dishwasher buying guide for a full checklist.
Popular picks include the BlastWash Pass-Through Dishwasher AT50H — the highest-traffic pass-through unit in this range — and the Asber Tech-Line Passthrough Hood-Type Dishwasher GEH500DD for a European-spec hood-type alternative.
Frequently asked questions
What is a pass-through dishwasher and when do I need one?
A pass-through (or passthrough) dishwasher has a door or hood on two opposing sides — dirty racks enter one side, clean racks exit the other. This one-directional flow suits kitchens with dedicated dirty and clean zones, preventing cross-contamination. It's the right choice when underbench units can't handle your rack volume or your kitchen layout requires separation of dirty/clean areas.
What is the throughput of a commercial pass-through dishwasher?
Hood-type pass-through units typically handle 40–80 racks/hr (comparable to a fast underbench unit) but with the one-directional flow advantage. Rack-conveyor pass-through machines process 80–120+ racks/hr for hotel and institutional volumes. Match throughput to your peak covers per service.
Hood-type vs rack-conveyor pass-through — which do I need?
Hood-type: the operator lowers a hood over the rack, runs a cycle, raises the hood, pushes clean rack out the other side. Suits 60–100-cover restaurants and cafés. Rack-conveyor: racks move automatically on a belt; suits 200+ covers or continuous institutional service (hospitals, schools, hotels). Rack-conveyor is a significantly larger capital investment.
Do commercial pass-through dishwashers require a licensed plumber to install?
Yes — connection to hot/cold water supply and commercial-grade drain lines must be done by a licensed plumber in Australia. Confirm compliance with AS/NZS 3500 and your local council requirements before fitout.
What is the warranty on commercial pass-through dishwashers?
Manufacturer-backed and varies by brand and model — see our warranty information page for full terms.
