DUST COMMANDER Crimp Protection Valve Cyclone Filter Plastic BarrelDUST COMMANDER Crimp Protection Valve Cyclone Filter Plastic Barrel

Crush protection valve for cyclone filter/plastic barrel.

Protects your cyclone filter system from damage caused by excessive pressure.

Protects the plastic barrel of your cyclone filter system from crushing.

DUST COMMANDER DUST-SP

Anti-squeeze valve for cyclone filter/plastic barrels.

This valve consists of a valve and adjustable spring and opens automatically to limit the maximum negative pressure inside a plastic barrel used with a cyclone separator, protecting it from crushing.

This valve is recommended for the use of the DUST COMMANDER CLC, DLX and HD models on plastic barrels (max. 60 litres recommended).

This valve does not make sense when used with our DUST COMMANDER XL and XL+ filters, as the negative pressure generated by HVLP systems (high volume, low pressure) is not enough to cause a plastic or power barrel to fall.

Also, the sets with DUST COMMANDER S30, S60, X30 and X60 steel barrels do not require the use/installation of this valve as they are strong enough to not collapse when the suction mouthpiece or suction hose is blocked.

Please note: The spring must be adjusted to keep the valve closed during normal use and only opens when the suction hose or suction nozzle clogs.

The problem

In normal operation, a slight negative pressure (a few ten mbar) is created in the dust container/collector of a cyclone filter system. This negative pressure is more or less pronounced depending on the performance of the vacuum cleaner and the diameter of the pipes used. Under these conditions, most plastic or power barrels are strong enough to not deform.

Unfortunately, in some cases, e.g. when squeezing or clamping the suction hose, the negative pressure inside the collection barrel drops to -250 mbar. This generates forces of several hundred kilograms on the walls of the barrel, which then collapses very quickly.

Our solution

To solve this problem associated with the use of insufficiently stiff barrels, we have developed an anti-squeeze valve.

This valve consists of a valve and an adjustable spring and opens automatically to limit maximum negative pressure inside the collection container.

The valve must remain closed during normal use and must only open when the suction hose is clogged.

Under what circumstances can excessive negative pressure cause the container/dust collector/chips to be crushed?

How to adjust the anti-squeeze valve

To adapt to the vacuum strength of your vacuum cleaner, the valve is equipped with an adjustment system. The tighter you tighten the nut, the stronger the spring is compressed and the higher the negative pressure of your vacuum cleaner must be to open the valve.

Tighten them to increase the maximum allowable negative pressure. Release them to reduce the maximum allowable negative pressure inside the barrel.

Too easy tightening leads to a loss of the effectiveness of cyclone filtering.

Make sure that you do not tighten the adjusting nut too tight, otherwise the valve will not open when the hose is blocked.
