An industrial vacuum cleaner can be a critical element to keeping a facility clean, but choosing the wrong vacuum can be costly and dangerous.
Industrial vacuums are available in all shapes and sizes and such a saturated field can make picking the most appropriate option overwhelming for maintenance personnel.
So how can facility managers ensure they are selecting the best solution for their facility?
Goodway Technologies, which provides innovative maintenance solutions for a wide variety of industries including commercial HVAC, food and beverage processing, power generation, and manufacturing, has offered five tips on how to select the best industrial vacuum cleaner for the job.
Determine the application
An industrial vacuum cleaner delivers the best performance when the features and specifications align with the intended application. Using the wrong vacuum will lead to poor performance and vacuum burnouts — a costly mistake. It’s essential to understand what kind of materials will be collected — from the smallest grain of powder to the largest piece of scraps.
From the size of the particles to whether or not they are flammable or combustible, understanding the environment and the material will assist in making an informed buying decision. Examples of the common substances an industrial vacuum cleaner is designed to handle safely include scrap metal, metal chips, coolant, dust, debris, paint powder, food particles, and floodwater.
The application’s consistency alone can help determine whether a wet vacuum, a dry vacuum, or a combined wet/dry vacuum is required. Dry vacuums are designed to pick up lighter particles, while wet vacuums use heavy-duty pumps to move dense, heavier liquids.
It’s recommended to purchase a vacuum that meets the primary application — whether it be for dry or wet applications. However, if there is a need to pick up both wet and dry substances, wet/dry vacuums can perform in both cases.
Identify the appropriate filtration system
One of the most frequently asked questions when purchasing an industrial vacuum cleaner for dry pickup is which filter is the best. The environment and the application strongly influence whether to use a HEPA or a Standard filter.
According to the Occupational Safety and Health Administration (OSHA), a HEPA, or high-efficiency particular air filter, is defined as a filter that is at least 99.97 per cent efficient in removing particles of 0.3 micrometres in diameter. To provide context, that’s much smaller than a coffee ground or even one single grain of cayenne pepper. HEPA filters were created to capture microscopic substances, like dust mites and other airborne particles that can be hazardous or cause health issues. Depending on the industry, there are strict maintenance guidelines that must be adhered to in order to clean a facility properly.
Standard filtration generally filters to around 10 microns and performs well for filtration of larger material pickup or areas where fine or hazardous materials aren’t being picked up. Standard filters would not be sufficient for higher-risk areas. While standard filters can certainly be effective, they don’t offer the same amount of filtration as HEPA filters. This is where understanding the environment can help determine which is the best solution.
Find out how much power you need
Some might assume that the motor’s horsepower rating automatically determines its ability to pick up materials. However, the horsepower of an industrial vacuum isn’t the primary factor that should be assessed.
- Airflow speed – If the application requires the pickup of dry materials, the airflow is a vital detail to consider. The airflow speed is measured by cubic feet per minute (CFM), and this force draws and collects particles inside the vacuum. The higher the CFM of the airflow, the more volume received when picking up fine powders, such as flour or dust particles.
- Static lift – The static lift is directly related to the power of the airflow and its ability to lift the material. Vacuums designed for lifting liquids or heavy metals will have high lift specifications. When suctioning fluids with heavy density, such as water, it requires a higher static lift and a lower CFM to allow the vacuum to lift these substances.
Understand the necessary capacity
An industrial vacuum cleaner doesn’t utilize small collection or dust bags that need to be frequently replaced. They are designed with a larger capacity to simplify the process and typically come in various sizes to meet different needs.
In addition to the size, the canisters where the debris or liquid is collected may also come with different features. For wet vacuums, consider an option with a tilting tank or pump to make it easier to remove the accumulated liquid.
Does it require special features?
An industrial vacuum cleaner has specific needs depending on what you’re vacuuming. The machine has to handle different substances that may cause problems if not appropriately handledm such as flammable or combustible substances. A good practice for choosing your industrial vacuum cleaner is assessing what materials and voltage you will use to maintain safety protocols. When cleaning areas where hazardous dust or liquid is present, vacuums should be explicitly certified for those material pickups. Using products that are not certified could result in catastrophic explosive results.
Finding an industrial vacuum cleaner that matches the environment and application will result in more effective and safe cleaning.
