Compact grease management
Passway™ | M-43F
A compact 40L Passway™ gravity grease separator for smaller kitchens, staff facilities and light food-preparation areas.
The M-43F uses controlled flow, internal baffles and gravity separation to reduce fats, oils and grease entering downstream drainage or treatment systems.

Product background
Small-format grease management
The Passway™ M-43F is suited to smaller kitchen applications where fats, oils and grease need to be intercepted before wastewater enters drainage, septic, greywater or wastewater treatment systems.
Lower-density FOG rises within the chamber while heavier material can settle. Internal baffles and the protected outlet reduce direct carry-over into downstream pipework.
The outlet remains wastewater. The M-43F reduces FOG and retained solids but does not produce potable, purified or disinfected water.
Best suited for
Compact kitchens and lower-load sites
- Domestic kitchens requiring source grease control.
- Staff kitchens and shared facilities.
- Small cafés and light food-preparation areas where the calculated loading suits the separator.
- Sites where installation space is limited.
- Kitchen wastewater feeding downstream septic, greywater or treatment systems.
Compact size does not establish suitability by itself. Select the M-43F from the connected fixtures, peak flow, grease and solids loading, connection configuration and required service interval.

Independent product evidence
Passway™ BS EN 1825-1 test programme
The Passway™ grease-separator range is supported by independent testing against BS EN 1825-1.
The M-43F forms part of that tested range. The exact nominal-size rating, laboratory flow configuration and numerical performance result should be matched to the model-specific test evidence when required for a consent, network or technical-submission purpose.
WCTNZ® does not apply the M-43D or M-43E numerical test result to the M-43F. Model-specific technical evidence controls where an exact laboratory result is required.
New Zealand compliance
Compact separator assessed on performance
The M-43F is smaller than the minimum physical volume used by the prescriptive G13/AS2 grease-trap Acceptable Solution.
Where the prescriptive Acceptable Solution is not followed, applicable BS EN 1825-1 evidence may form part of a project-specific Alternative Solution together with suitable sizing, plumbing, drainage, installation and maintenance information.
Building-consent, wastewater-network and trade-waste requirements must be checked for the proposed installation.
WCTNZ® support
Passway™ product and technical guidance
WCTNZ® supplies and supports Passway™ grease-management products in New Zealand and can provide product information and practical selection support for proposed installations.
