NEWSCRUB AH 300 PLUS ROASTER is the 2,500 m³/h size of the NEWSCRUB AH ROASTER water scrubber: recirculating hydrodynamic washing for smoke, grease and odours from charcoal grills.
NEWSCRUB AH 300 PLUS ROASTER
The unit is installed on the hood extraction duct. Water sprayed by the nozzles wets the particulate and grease, makes them heavier and carries them into the collection tank, where they settle.
The data on this page come from the NEWSCRUB AH ROASTER series datasheet, Rev. 01-2026.
AH 300 PLUS has a datasheet with air flow, dimensions, connection diameter, water content, recirculation pump and power supply.

The hood air flow decides the size
AH 300 PLUS reaches 2,500 m³/h. The series covers 2,500 to 14,000 m³/h in five sizes. The final check is made on the real system.

The problem
Smoke, grease and odour from charcoal cooking
Grill smoke carries carbon particulate, grease and odorous compounds. Without treatment they settle in the duct and reach the discharge.
Grease and soot settle on the inner walls of the extraction duct.
Untreated particulate reaches the extract fan and fouls it.
The remaining odour can be noticed outside.
How it works
Recirculating water washing
The air enters the washing chamber. The nozzles spray water onto the flow, baffles increase contact and the wetted particles settle in the collection tank.
Spray water onto the flow
Washing layout of this size: 8 nozzles: 3+3 stages + 2 in the hopper.
Increase contact
Baffles guide the air through the washing stages, so contact between water and air lasts longer.
Collects and returns the water
The tank holds 140 l; the 1.3 kW pump returns the water to the nozzles. It is not a once-through system: the tank is emptied and cleaned periodically.
Installation
In line on the duct, with the tank accessible
The unit is installed on the hood extraction duct, in line or in a branch depending on the space available. The tank must remain accessible for emptying and cleaning.
This size has Ø 300 mm connections and a 140 l tank.

In short
The stated air flow is the maximum value with the extract fan intended for the size. The real air flow depends on the pressure losses of hood, duct, bends and discharge.

| Model | Air flow with extract fan | Connection Ø | Water in tank | Recirculation pump | Washing | L × D × H | Power supply |
|---|---|---|---|---|---|---|---|
| AH 300 PLUS | 2,500 m³/h | Ø 300 mm | 140 l | 1.3 kW | 8 nozzles: 3+3 stages + 2 in the hopper | 1,050 × 750 × 960 mm | 230 V · 50 Hz · 1~ |
Power supply 230 V · 50 Hz · 1~, recirculation pump 1.3 kW, 140 l tank. Values from the series datasheet Rev. 01-2026.
Anchoring
Fixing and access to the tank
The unit is fixed on the duct or on a dedicated supporting structure, with the tank accessible for emptying.
- Supporting structure suited to the machine weight and free from vibration.
- Metal brackets sized with a margin over the declared weight.
- Provide the tank drain and space for internal cleaning.
- Handling with pallet truck or forklift depending on the size.
The actual weight is on the transport document and must be used to size brackets and lifting equipment.
Declared values
The data of this size
Values from the series datasheet. Final sizing depends on the source, the real air flow and the pressure losses of the system.
The number and layout of the washing stages depend on the model; the actual supply is defined in the quotation.
