PRODUCT OVERVIEW
Foam solution.
Air. Controlled discharge.
The MEFG uses air aspiration to turn a proportioned foam solution into a medium-expansion foam discharge. Solution passes through a calibrated nozzle, inducing atmospheric air before moving through the stainless-steel foam-generating screen.
A matching inline inductor or suitable proportioning system supplies the required foam solution. The generator is intended for an engineered fixed or semi-fixed arrangement, with concentrate selection, inlet pressure and discharge clearance matched to the protected hazard.
Foam-generating screen
A stainless-steel mesh forms the aspirated solution into medium-expansion foam.
Matched proportioning
A compatible inline inductor or proportioning system supplies the selected foam concentration.

OPERATION
Prepare the system.
Establish the foam discharge.
Catalogue guidance used with the approved fire-protection system procedures and selected foam concentrate.
- 01
Prepare the installation
Follow the approved system layout, flush supply piping before installation and keep air inlets and the foam discharge path unobstructed.
- 02
Supply proportioned solution
The fire-protection system supplies the selected water and foam-concentrate mixture when activated.
- 03
Induce air & form foam
Solution passes through the calibrated nozzle, induces atmospheric air and moves through the foam-generating mesh.
- 04
Discharge & shut down
Foam discharges into the selected hazard area. Control operation and shutdown according to the approved system procedure.
CONFIGURATION & ENQUIRIES
Specify the complete
operating arrangement.

INSPECTION & MAINTENANCE
Keep the air path clear.
Maintain the assembly.
Use the catalogue inspection intervals within the facility’s approved maintenance programme. Confirm the concentrate manufacturer’s cleaning instructions.
01Monthly inspection
- Inspect the body for physical damage, corrosion and coating deterioration.
- Keep air openings clear and check pipe connections for leakage.
02Quarterly maintenance
- Inspect the screen for dirt, corrosion or blockage; clean with water and a soft brush.
- Check the inlet nozzle, mounting brackets and supports.
03Annual checks
- Carry out an operational discharge test where permitted and verify expansion and discharge performance.
- Inspect seals and connections; replace damaged mesh or worn components and confirm compatibility with the concentrate in use.
04Cleaning & protection
- Do not paint or obstruct the air openings or use metal tools that could damage the screen.
- Flush after testing when recommended by the foam-concentrate manufacturer. Protect the equipment from dust, insects and debris.
