Dust characteristics that determine the correct dust collector
Choosing an industrial dust collector should begin with the dust, not the equipment catalogue.
Indoor or outdoor dust collector installation: Which is better?
Choosing where to install an industrial dust collector is an engineering decision, not simply a matter of available floor space.
The function of explosion vents and explosion isolation valves in dust filtration systems design
Why combustible dust needs special attention Many South African production plants generate fine dust during cutting, grinding, conveying, mixing, sanding, tipping, bagging or material recovery. Dust from wood, grain, sugar, plastics, coal, certain metals and other dry powders can become combustible when suspended in air at the right concentration. In a dust filtration system, the […]
Common dust collector system design mistakes that reduce performance
In South African industrial environments, a dust collector is not simply a machine placed at the end of a duct. It is part of a complete air filtration system that must capture dust at the source, move it through correctly designed ducting, separate it efficiently and discharge the collected material safely. When the system is […]

Oil mist in a CNC workshop is not just a housekeeping problem.
Why Nederman Hose Reels are a top choice for industrial applications
Choosing the right hose reel is not only about keeping hoses off the floor.
When to add a pre-separator cyclone: Reduce filter loading and fan energy
A pre-separator cyclone is a first-stage separator installed ahead of the main dust collector. Its purpose is to remove the heavier, coarser fraction of dust before that material reaches the bags or cartridges. Nederman describes pre-separator cyclones as equipment used to separate larger particulates and increase filter life. In other words, a cyclone is not […]
Air filtration: What “industrial air filtration” means (and when gas-phase filtration matters)
Industrial air filtration is broader than dust collection. In South African workplaces, it can mean controlling both particulate contamination and gaseous pollutants that affect worker safety and compliance.
Rotary valves for dust collector systems in South Africa
A rotary valve (often called a rotary airlock) fitted under a dust collector hopper, controls how collected dust is discharged while helping the filtration system hold its designed pressure balance.
Explosion venting on dust collector systems in South Africa
Many South African plants generate combustible dust during conveying, grinding, mixing and bagging.Dust collectors (baghouses and cartridge filters) remove that dust from the air but they also confine fine particulate in a vessel, which can support a rapid deflagration if an ignition source is introduced. How explosion venting works Explosion venting provides a controlled route […]
Dust collector maintenance and troubleshooting: Keep dust filtration performing
A well-maintained dust collector protects people, product quality and equipment while keeping your dust filtration system delivering stable airflow. When performance drops, costs rise fast through higher energy use, unplanned stoppages, and premature filter changes.
Dust filtration design in South Africa: Capture-at-source extraction that works
Effective dust filtration design follows a simple rule: capture the dust cloud before it spreads. A dust collector (including a baghouse filter) can only perform if the hood, ducting and airflow are designed correctly.

Powder coating dust collection
Powder coating is a dry finishing process that sprays finely ground electrostatically charged particles of pigment and resin onto grounded parts. These particles stick to the parts until they are melted and fused into a coating in a curing oven. This process is suitable for various materials including metals, plastic, glass and medium density […]
Why is conveying velocity so important in ducting design?
Conveying velocity within the ducting design is very important to ensure that dust particles from the dust collector move through without collecting within the ducting system. Should the particles move too slowly or too quickly it can be problematic. Envirox understands that when airflow is not set at the correct speed problems can occur, and […]

Do I need a Dust Collector for a welding fumes extraction system?
When purchasing a welding fume extraction system, companies often debate on whether they need to incur the cost for a dust collector as well. If the aim of installing a fume extraction system inside the workshop is to rid the air of dangerous fumes and dust, then why should a dust collector also be installed […]
Oil mist in a CNC workshop can be problematic
The inhalation of coolants and oil mist particles while working with CNC lath, milling and grinding machines is extremely hazardous to employees on the workshop floor. When the door is opened on these machines to load new steel parts the oil mist and coolant aerosols escape. These particles can settle on the floor, on the […]
ESD (Electrostatic Discharge) extraction arms for soldering in electronic component manufacturing
Soldering is an important process when connecting electronic circuits where the conductors carry electronic signals. Soldering occurs when two electrical components are joined with a solid conductive connection. If this conductive connection is not solid, this could result in temporary breaks or fluctuations in the circuit which could interrupt the signal being sent. During the […]
Dust filtration for crusher plants
Due to the size of iron ore when it is mined, the rock needs to be crushed and screened to the desired size. During the crushing and screening process, a large amount of dust is expelled which settles all around the working area. Often downtime is needed for cleaning and maintenance to occur due to […]
Envirox sells dust Collectors with Nanofiber cartridges
Nanofiber technology has allowed filters in dust collectors to be able to collect smaller particles than before. This is done by using less fan and compressed air energy, with the filters lasting longer and needing less maintenance than other filters. The nanofiber is applied through a spraying process to the filter’s surface which creates a […]
Vehicle exhaust fumes – increased risk during South African winter
During the colder months more often than not, the doors to the workshop floors are closed to retain heat and for employees to keep warm. The same goes for vehicle service stations and repair shops, and what many don’t realise is that when this is done, all the fumes are kept inside rather than dispersed […]
Extraction at source: The solution for fume and duct extraction
When industrial applications emit dust and fume particles, at source extraction is the safest and most cost-effective solution to preventing the particles from escaping into the air.
