Stop salt mist & spray from entering your engine room.
Salt spray and mist in your engine room has traditionally been one of the most difficult issues to control. Now with Marine Air Flow moisture reducing air intake grilles, you can remove the problem altogether. Damage such as blown turbo's, blocked air filters, wide spread corrosion and degradation of your valuable engine room equipment can now be avoided.
Features of our air handling units include, reduced damage to valuable plant and engine room components, custom made to suit your unique vessel requirements, no moving parts for affordable maintenance and they are supplied with a full installation kit and instructions.
Using engine induction or engine room fans, the moisture laden external air supply is drawn through our grille, passing through a complex system of vanes in the process. This action removes the moisture laden molecules from the air, leaving behind a considerably fresher air supply inducted into your engine room.
How Our Mist Eliminator Grilles Work
01
The moisture laden air is drawn into the face of the grille.
02
It then passes through a system of vanes which trap the moisture in the air and cause it to run vertically down the face of the vanes and then be expelled via the external drain.
03
The moisture reduced air is then fed into your engine room for use by your engine and other components.
04
The vanes are sufficiently complicated to trap the moisture, but not so complicated that they significantly slow the air flow.
Air Intake Grille Sizes and Shapes
While we do have some standard sizes and shapes for our intake grilles, a lot of our projects are custom shapes to suit vesells and client requirements. View some of the unique sizes and shapes of Air Intake Grilles we've made to date.
Please note however that the size of the grille (or grilles) you require, is directly related to how much air you need, the size of your engine room and its components.
Ventilation Grilles Flange Info
01: Flush Flange
With this option the fixing flange is flush to the outside face of the grille. Once installed only the 3mm thickness of the flange protrudes outside of the vessel. 100mm of the grille thickness extends into the air ducting, reducing the airway by 100mm. The drain slots on this assembly are totally visible to the exterior face.
02: Stepped Flange
With this option the grilles extend 30mm to the exterior of the vessel and 70mm protrudes into the air ducting. On this assembly the drain slots maybe mounted on the underside edge and thereby are not easily visible. This achieves a more aesthetic external appearance.

03: Limited Flange
With this option the grille extends 70mm to the exterior of the vessel and only 30mm protrudes into the air ducting. This achieves the least restrictive passage within the air ducting. It is recommended that this arrangement is utilised in any restricted airway so as to maximise air flow.
03: Fixing Flange
The fixing flange is the area that surrounds the grille used for fixing the grille in place.
This is a standard size and is 40mm.

Air Intake Grille Video Demonstration
The video below should help you to understand how our Air Intake Grilles actually work.
Our Grilles have no moving parts so you don't have to be concerned with tricky maintenance challenges, and in over 12 years in business we've never had one single failure, provided of course they are installed correctly. We did have someone install them back to front once but that was easily detected and corrected. They shall remain anonymous and it did expose something that we could improve upon. All our grilles now come with directional stickers so that can't happen again.
This short 2 minute video is a walk around that shows you how the grilles work. Please let us know any questions you might have and we would be pleased to answer them.
