Industrial Vacuum Systems

Industrial vacuum systems are often used for on-point or at source extraction and the general cleaning of a working area. This variant of LEV is especially used when the process produces a high energy contaminate cloud with high velocity, they can produce high pressure but capture low volume much unlike a traditional LEV that typically is more capable of the opposite.

There are several methods to consider when choosing the correct solution for your requirements. Per example, depending on the application, number of operators and space available, a versatile mobile solution can be introduced. They can be used to capture at source by being directly attached to the piece of equipment using a series of connectors and flexible hose. They can be built to different standards by a range of manufacturers incorporating a variety of safety features designed to protect the user and the equipment, whilst also maintaining the level of protection as required by the HSE. In general, any working environment should look to use M class equipment as a minimum. Despite their chosen features which are an airflow warning light, HEPA H13 filters and disposable bags, M class extractors can handle mid to high toxicity dust, such as silica and asbestos, whereas L class will not be able to handle such toxicities.

Furthermore, and depending on the manufacturer’s options, these can be supplied with a single-phase 110v or 240v fan, or a three-phase fan with 400v supply, granting even greater flexibility when choosing the correct solution. Similarly, should there be a heightened volume of material then waste capacities can be increased using a mobile pre-separator or larger collection bin and bags. Likewise, they can be constructed to ATEX rating capable of handling various types of potentially flammable substances such as flour, carbon fibre and the like.

Predominantly end users favour a mobile industrial vacuum when there is a requirement for change. Operators visiting multiple sites and undertaking a variety of activities will need their vacuum to be portable. As well as this, mobile vacuums can be used parallel to a pre-existing LEV or general ventilation system as an additional level of protection, or simply introduced when there is a single process emitting contaminants at a greater velocity than that of the rest of the production and working line.

Central industrial vacuum systems offer a more permanent solution where large areas need to be covered and typically feature a filter chamber, vacuum pump or radial blower (fan) and pipe system with multiple inlets where there is a need for greater volume to be transported, or there are multiple points of extraction. To fulfil the parameters set by the HSE these can be constructed to the same minimum standard as the mobile M class vacuums, but with greater features such as automated filter cleaning, accessible control panel with fan speed inverter and much larger waste capacities provided by a combination of bigger filters and separate dust collectors with larger bags or bins. And much like the mobile equipment there can be many options to consider ensuring the system is the correct solution for your process.

Should you have various enclosures and rooms then the duct system can be installed in such a way that potentially only one dust collector is required. For example, a duct system with drop down points and these points can incorporate a shutter valve, flap valve or can remain constantly open depending on how the system and the fan timing has been designed. Flexible hose, extraction arms and or custom plenums can be implemented to capture at source.
