Why the HEY BRUSH is a vital part of your equipment to help clean to TR/19 and how it is more versatile.

There are several different companies making brushing machines for air ducts, but how many really understand what is required for using in Grease Ducts? Not many is the answer.
When there is a requirement for a brushing machine to be used, the operator will have PPE on and this will include gloves suitable to protect from the choice of chemical. So, keeping the operation and process as simple as possible is what is really required. The HEY Range of brushing machines are made to last and simple to use. All you need a machine to do, is brush right, brush left, spray foam and keep straight in a duct. This sounds simple but I believe Hey Cleaning Technology are the only company to perfect this without damaging or breaking the head of the machine.
For horizontal ducts or larger vertical ducts, you need to use a centralizer to keep the brushes straight in the duct. Using an air powered centralizer is good while going forward, but when you want to come backwards, the wheels and legs have no give in them and get stuck on the flanges between the sections of duct. When cleaning visibility is an issue, so you can’t see the problem and operators on the machine will pull the hose and this will weaken the head and torsion bar inside, contributing to the head breaking. 
What is required is a centralizer that can be set at different angles and can be used in any shape or duct up to around 950mm. The Hey Centralizer combines flexibility and the ability to position the brushes where you want them and not just in the middle of the duct. So for instance, if you need to brush down the right hand side of the duct, extend the left legs to position the brushes tighter to the right side, cleating more agitation on the duct. All that is needed is a simple twist with an Allen key to reset the centralizer and reposition the spring-loaded legs.
The Hey Brush itself has the added safety of the controls being on the top of the machine and not inside the reel itself. I have seen firsthand an arm being broken when an operator pulled the hose, while his colleague was changing the brush direction. All the components of the machine are inside the frame of the machine. When you are manoeuvring the machine around, you can’t see the sides and going through a door or tight area, you don’t want any external parts as they will break when making contact with door frames, walls, getting the machine in and out of the van and also travelling in the van. We have also made the machine to be considerably lighter than the other similar machines, as sometimes it is needed to carry the machine upstairs, so the lighter the machine the better!
All in all, Hey Cleaning Technology have really put a lot of thought into building the best machine available for cleaning grease ducts. With the added luxury of being compatible and working together with the Foam Box, we think we are giving our customers the best in Class!
