Dense phase pressure system with Air Assist
– Lower pressure than conventional dense phase resulting in lower velocities and overall energy.
- Air is introduced at the top of the transporter as well as at various locations in the convey line.
- Compressed air required at 30 – 50 psig.

Advantages:
· Allows for much longer distances
· Much more efficient than “Blow-Pots”
· Lower velocities, Ideal for fragile or abrasive materials
· Can handle most types of materials, except large particle size (1” and greater)
· Can stop/ start system with a full line
Disadvantages:
· Transport vessel requires substantial head-room as compared to dilute phase
· Greater expense than blow-pot system without air assist technology
