Passway™ Technology

Passway™ grease traps are built around a simple physical principle: control the wastewater flow so fats and oils can separate while heavier solids settle or are retained.

Instead of allowing FOG to travel further through downstream pipework, the grease trap becomes an accessible capture point where separation takes place before the wastewater continues through the drainage system.

Separation

Using gravity and controlled flow

Fats, oils and grease are generally less dense than water and naturally rise when the wastewater flow is slowed sufficiently.

Passway™ internal baffles help manage the flow path through the chamber, allowing FOG to rise and heavier material to settle while reducing direct carry-over toward the outlet.

Solids control

Intercepting food-related solids

Depending on the product, removable baskets and internal components help intercept food-related solids before or within the main separation chamber.

Removing this material during routine servicing helps preserve the available separation volume and reduces the amount of retained material reaching downstream drainage.

Construction

Designed around accessible maintenance

Passway™ grease traps use polypropylene construction together with model-specific cover seals, locking components, internal baffles and air-management features.

These components are designed to remain accessible so they can be inspected, cleaned and correctly reassembled during normal maintenance.

Important: the outlet remains wastewater. A Passway™ grease trap reduces fats, oils, grease and retained solids but does not produce potable, purified or disinfected water. Passway™ grease traps are intended for kitchen and food wastewater rather than petrol, diesel, motor oil or other light mineral liquids.

Performance evidence

Independent testing against BS EN 1825-1

The Passway™ grease-separator range is supported by independent testing against BS EN 1825-1, an international grease-separator product-performance standard.

Exact nominal sizes, tested flows, connection configurations and laboratory results vary by product and are therefore stated on the relevant product page or technical documentation rather than applied generally across the range.

New Zealand use: applicable BS EN 1825-1 evidence may support a Building Code Alternative Solution where the complete installation is assessed against the relevant G13, sanitary plumbing, drainage, servicing and wastewater-network requirements.
