The CamVac extractors, are machines for aspiration of waste and chippings. 

They key of the CamVac extractors, is power, that is the union of two key units: pressure and volumetricflow rate.

Volumetric flow rate: this is a measure of the amount of air moving through the system. A single CamVac motor gives a volumetric flow rate of 55 litres for second and this rate increases with each additional motor fitted to a machine.

Pressure: this is the pressure differential the motor creates during operation. Each CamVac motor is capable of producing a maximum of 21 kPa (kilopascals) of pressure. When extracting finer materials, such as wood dust created by a sanding machine or a bandsaw, a larger
diameter extraction hose, usually 4”, is recommended. This is because fine wood dust, being much lighter than chippings or shavings, does not need as high a velocity to keep it moving through the system. 4” piping is also very useful for minimising blockages in the dust extraction systems of woodturners who produce long shavings, which can collect in clumps and cause obstructions. By comparison, chip extractors and cyclone extractors are missing one key element: This element is pressure. The very small amount of pressure created by a chip extractor means that any changes to hose diameter will ‘throttle’ the pressure even further, eliminating it to the point that the extractor becomes ineffective. This is precisely the reason chip extractors and similar machines are incompatible with small diameter hoses and cannot therefore be used with, for example, power tools, which traditionally require relatively small diameter hoses to be connected to them, usually 32 mm.

CamVac machines work incredibly well with power tools as they can easily cope with hose of this diameter.

To filter fine dust using a chip extractor, the filter’s surface area must be exceptionally large in comparison to CamVac filters in order to compensate for the airflow restriction caused by the introduction of the filter. Because CamVac machines have high levels of pressure, the filters can be relatively small and fit inside the drum of the machine. This is because the increased restriction to airflow, or pressure drop, is compensated for by the motor – therefore CamVac extractors can be very compact, which is a real benefit to the design, saving you valuable workshop space.

It is important to minimise the number of bends in the ducting system: bends create drops in pressure, therefore reducing volumetric flow rate and ultimately, power. Of course, virtually all systems will need bends, but minimising them with forward planning and good design can make a big difference to the effectiveness of your system. Using smaller diameter ducting in an extraction system can create the optimal system, which is why 2 ½” ducting is a popular size for this purpose. This will, as explained above, increase the velocity of waste, allowing it to stay airborne within the system. Another key factor that affects performance is the number of motors on the extractor that is used to power the system. The greater the volumetric flow rate of a system, the more effective it will be. Therefore, we recommend a minimum of a twin-motor extractor for a workshop system and ideally a triplemotor extractor, if a particularly large system is being installed. As the length of hose used increases, it can be seen that the volumetric flow rate reduces very gradually.

Low Noise Output: CamVac machines are probably the quietest High-Pressure-Low-Volume. The motor exhaust and cover design effectively reduce noise during operation. When using the optional hose in the motor exhaust, noise can be reduced even further by directing the open end of the hose outside the workshop, for example through a window.

Three-Stage Filtration to 0.5 Microns: The drum filter and motor filters give three-stage filtration for fine dust, using two washable cloth filters and a paper filter system. Models with multiple motors can either give increased suction power when using all motors together or each motor can be used in turn, giving longer operation times. All CamVac models feature a unique cyclonic inlet system, which draws the waste around the sides of drum and away from the filters and motors, increasing their lifespan.
