AutoAire automatic dust extraction
system
The new AutoAire cut-off gate is a double win in energy and equipment-cost savings for any shop with a central collection system for dust, fumes or mists serving intermittently operated machines
The AutoAire gate automatically opens needed duct branches when a machine is turned on, while closing off inactive branches and machines This fully utilises the pick-up power of a collection system by applying as much vacuum as possible, only when and where needed, allowing a smaller fan - with smaller energy bill - to handle a system with many branches

Centrifugal fans offer high flow rates
A range of centrifugal fans, designed with fume extraction in mind, are single inlet types, with forward sloping blades and offer flow rates of up to 3185m3/hr (1875ft3/min).
Safety and security products save money
Specialising in systems for safety, security and control for vehicles, plant and machinery, systems are tailored for industrial use and often pay for themselves on reduced insurance premiums alone.
AutoAire gates often "conserve" capital equipment costs, too.
They allow sizing of the collector system based on the true usage, rather than the total requirement.
This can significantly reduce the size and cost of the system.
AutoAir gates may also eliminate the need to purchase a larger collection unit as a plant adds branches to a duct system over time.
AutoAir gates are easily installed in the air-handling ductwork.
Wiring is simple: a single wire connected to a machine, such as a saw, can control one or more gates as it is turned on/off.
No special control is needed.
In large collection systems using a VFD fan (variable frequency drive), the gates can be used to minimise fan speed - and power requirement - in proportion to the number of open gates in the duct system.
Using 75-psi air via 0.25in tubing, the cylinder on each gate fully opens or closes the gate in response to a dust/fume "source" being turned on or off.
This eliminates problems that occur with manual gates when employees don't close them or damage them.
AutoAire gates come in various sizes.
Gates 3in to 9in in diameter use one air cylinder.
Gates 10in and above use two.
The switching solenoid for the compressed air can be activated by 12V, 24V, or 120V AC/DC.
