When discussing mounting kit designs, most of the concerns and conversations revolve around the strength and materials of the bracket and coupling. These components are indeed critical; however, when is the last time you discussed fasteners in detail? These often-overlooked components are trusted to unfailingly connect the bracket between the valve and actuator.

Locking kits are used with automated valves to prevent valve rotation, i.e. “locking out.” This device is engineered to keep a valve in a safe, locked position, either open or closed. This allows the maintenance team to safely and securely work on other parts of the system without concern that the valve will be accidentally actuated.

The VanAire DAF design has a timeless approach to wastewater treatment; our exclusive aeration system combined with a durable design has outlasted even the closest competitors. VanAire’s wastewater pretreatment DAF technology is the most effective and reliable in the industry. Our MicroAire aeration technology and clarifier design maximize the removal of TSS, BOD, and FOG in all industrial wastewater streams. All VanAire DAF units feature our proprietary Breakout Valve that precisely controls the micro bubble cloud.

The Aeration Pump discharges at 105psi, air is injected and dissolved in the Saturation Tank then carried to the Breakout Valve where a pressure drop is controlled by an adjustment of the handwheel on the Breakout Valve.  This pressure drop causes saturated air to come out of solution creating a fine bubble cloud.

A ball valve is mounted on top of each Saturation Tank. They vent a small amount of surplus air to avoid turbulence caused by large bubbles in the DAF.

Injected air volume is adjusted and monitored with one Rotameter per Saturation Tank.

Modular aeration skid, common to our 150gpm, 300gpm (shown), and 450gpm aeration units, has a footprint of “approximately” 6′ x 4′ and stands 6′ tall.

100GPM and larger aeration pumps and motors are mounted on a subassembly which is attached to the main aeration skid via three spherical washers to reduce external force inputs that influence pump and motor alignment.
