The HDV 8000 vacuum conveying system has the highest performance and is the most energy efficient vacuum conveying system offered by Dynamic Air. It is our best vacuum system for conveying materials that are very fragile, abrasive, heavy, light, fine, coarse or difficult-to-handle.

This system operates with a very high solids-to-air ratio and has the ability for very low conveying line velocities. This enables fragile materials to be conveyed with minimal degradation and abrasive materials to be conveyed with very low wear on the system.

The HDV 8000 system is similar to the HDV 6000 system with the exception that it uses Dynamic Air's exclusive Dyna-Chek 4 booster fittings. The booster fittings provide added performance and much better reliability for most materials being conveyed. The system can be easily operated in the Full Line Concept mode for ultimate control in conveying most materials.

The primary power source is a high pressure vacuum pump that can produce up to 29 inches of mercury. With the HDV 8000 system, you can determine a conveying velocity that suits your material — not the other way around. Typical terminal conveying velocities are from a low of 50 feet per minute up to 800 feet per minute. For optimum performance, the conveying distance should be limited to 100 feet.

Primary components of the HDV 8000 system include a pickup nozzle at the beginning of the system; a vacuum conveying line with couplings and tubing bends; Dyna-Chek 4 booster fittings; a vacuum filter/receiver; a secondary filter; and a high pressure vacuum pump. For continuous conveying applications, a gatelock hopper with an inlet and outlet valve is installed at the end of the system.

Unlike the HDV 6000 system where all the air needed to convey is added at the start of the conveying line, the HDV 8000 system requires only the displacement air to be added at the beginning. The balance of the air needed to convey is then introduced through the Dyna-Chek 4 booster fittings that are spaced along the conveying line.

At the start of the system, material is flood-fed into the conveying line inlet, eliminating the need for metering of the material. The material and air move through the conveying line to the vacuum filter/receiver. As material enters the vacuum filter/receiver, the conveying air is separated from the material and the air passes up through the filter media and then through a secondary filter before entering the vacuum pump.
