How To Select From A Range Of Dedusting Filters

The use of dedusting suction systems in the workplace is critical to ensuring healthy air for your workers.

Beyond the health and safety of your workers, however, dedusting systems also deliver minimal air pollution which is also beneficial for other machinery and systems used within your business. Not all dedusting systems are made equally, which is exactly why you need to have a good idea of which you will need for your own business.

The key is to understand what systems are available and what the needs of your company are. To support you in this, let’s take a look at the range of systems and how to decide on the right option for you.

1. Dedusting System Filters

The fundamental difference between systems is the way in which they filter the air. Here are the most commonly-used options which you have before you here:

2. Cyclonic Filter

A cyclonic filter utilizes gravity and a centrifugal force to help separate particles in the air which is being sucked through. A cyclonic filter pushes the air into a tornado-like whirl, resulting in larger particles such as dust and pollutants being separated from the cleaner air with smaller particles.

3. Bag Filter

The bag filter uses mechanics to drive air through the porous bag, stopping the larger pollutants and allowing clean air to come out the other side. This is a highly effective system that can trap as much as 96/97% of any particles sized one micron or higher and is a very efficient dust collector.

4. Drum Filter

These can be attached to both mobile and fixed vacuum hoses and is in continuous operation. Drum filters have a high filtration capacity, they can be precisely designed for any application where you will use and they are seen as a very low maintenance option.

5. Venturi Scrubber Filter

The Venturi effect describes fluid pressure being reduced as a result of fluid flowing through a constricted tube or pipe. This filter utilizes the Venturi effect and as pressure is reduced it sucks through the mixed air flow in order to remove pollutants and dirt particles.

Deciding on Which Is The Right Choice

Let’s take a look at what you should be considering before you opt for any particular filter.

I. Dimensions

Initially, you need to think about what sort of space you have to play with inside the business. Some of these filters are extremely large which will pose a challenge if you are operating in a space-restricted location.

II. Maintenance

All filters will require some level of maintenance from you, but there are some which will require more than others. A bag filter for example, will need to be replaced frequently, which could include further costs and installations. Alternatively, you may look for a drum filter that won’t need much attention but will require regular checkups to ensure that it is functioning well.

III. Appliance Specific

If it is the case that you only have one or two appliances that produce high levels of dust particles, you may be better off buying filters solely for them. This could be a smarter option than looking at a large filter for the entire workspace.

And finally always rely on the data, a simple and low-cost assessment will be able to tell you just how much dust is in the air and what risk there is to human health. This could also influence your decision around which filter to buy.
