Basic Airlift Systems transfer items between two similar Send/Receive Stations through a single interconnecting tube.
For installation where limited space or building obstructions won't permit standard 48-in. radius bends, 24-in. radius
expanded bends are available that allow the free travel of Carriers without binding. Expanded bends can be used for
upward, downward, or horizontal runs.
Two Configurations of Send/Receive stations are available for use in the pressure/pressure Airlift systems, depending
on the user's station mounting requirements. The Type I Station suits narrow and taller mounting spaces, whereas the
Type II Station fits wider and shorter mounting locations. Both Stations are fabricated from 16-gauge cold roller steel
with an enamel finish. Station doors are manufactured from heavy steel.

Airlift Pneumatic Systems can deliver anything that fits in an Air-Lift Carrier to any remote location - even on different
floors or in other buildings - in a few seconds. Small parts, orders, invoices, credit cards, shipping papers, memos,
currency, mail, laboratory or test samples, medical supplies, or any other load weight up to 5 lbs, are whisked at speeds
up to 25 feet per second on a jet-stream of low-pressure air to a destination up to 2,000 feet away. Flexible systems
deliver upward, downward, or in any direction, not just horizontally. And they are energy-efficient; the blower operates
only when a Carrier is in transit, not 24 hours a day as many other system do.
Unlike old-fashioned, bulky, twin-tube vacuum systems consisting of heavy steel tubing and low-capacity carriers plus
expensive three-phase turbo-compressors requiring additional complex controls, the Air-Lift Pneumatic Systems are
compact and high-capacity, providing two-way carrier travel in a single tube. Conveying tubing and bends are made from
either strong, lightweight, non-corroding, dent-resistant PVC or optional steel, with diameters of 3 in., 4 in., or 6 in. And
unitized Send/Receive Stations with built-in turbo blowers can sit on desks or tables, or mount easily in a minimum of
space on walls, building columns, or any convenient flat surface, without using prime plant floor space. Installation is so
easy, your own employees can set it up in less than a day! No complicated power wiring. Just plug system into an
existing wall outlet.
Air-Lift Carriers are made from durable, high-density polyethylene for excellent wear in system-compatible diameters
of 3 in., 4 in., and 6 in., and standard lengths of 10 in., 12 in., and 14 in. Their smooth surfaces and aerodynamic design
generate minimal friction, permitting dramatic increases in system capacity and length.
Thousands of pneumatic tube system users are proving the cost efficiency of Air-Lift Pneumatic Systems in such diverse
installations as:

• Auction Houses
• Auto Dealers
• Brokerage Firms
• Railroads
• Restaurants
• Motels & Hotels

6" AIR-LIFT CARRIERS
For loads up to 5 lbs. And distances to 1,000 feet. Provides
4-3/8" useful diameter by 12" or 16" length - more capacity
at 1/3 the weight of ordinary carriers.

All of these safety and control features are standard and built into Air-Lift Pneumatic Systems, not added at extra cost.
• Exclusive electro-mechanical safety Door Locks prevent access to the send/receive compartments while a Station is
   in process of receiving a Carrier. Fully automatic. No user action required.
• Trapeze-design swing arm assembly prevents Carrier from entering receiving Station when the door is open. No more
   banged fingers!
• Red signal light on receiving Station indicates system is in use; automatically extinguished when Carrier arrives at
   receiving Station.
• White signal light indicates Carrier arrival in Station; automatically extinguished upon removal of Carrier from
   compartment

A unique option available on Air-Lift Pneumatic Systems is Variable-Volume Speed Control. Engineering excellence has
developed this entirely new concept in point-to-point pneumatic tube systems, that of using variable air volume to:
• Control Carrier speed
• Reduce the force of Carrier impact upon arrival
• Reduce the noise of Carrier impact.
• Produce a smooth, non-turbulent, jolt free transmission of the Carrier's cargo.
Variable-Volume systems produce a smooth, gentle Carrier ride on a cushion of air and a pillow-soft landing on the
arrival pad!
The keys to this innovation in pneumatic tube systems are two adjustable timers. A pneumatic tube system requires the
most air pressure to lift the Carrier out of the Station and through its initial vertical rise. But, once the Carrier is level,
the system's power requirements drop significantly to just enough pressure to overcome any friction between the
Carrier and the tubing walls.
Variable-Volume Carrier Speed Controls are standard in 6-in. systems, and available at nominal cost in 3-in. and 4-in.
systems.
Another design for carrier slowdown is a relief valve, triggered by air pressure, that controls the Carrier as it reaches
the point of final descent into the terminal Station. This valve vents system pressure and allows the Carrier to fall
unpowered into the Station. To counteract the pull of gravity, a second valve simultaneously builds up back pressure
to cushion the Carrier's fall to soft and gentle landing on the arrival pad. The total result is a cargo that rides smoothly
and arrives unshaken.

CUSTOMIZED SYSTEMS FOR SPECIAL APPLICATIONS
In addition to the standard sound-absorbing special gaskets and foam Carrier arrival pads used in all Air-Lift Send/Receive Stations to dampen noise-producing vibration and Carrier impact shock, we offer the user a choice of different options
that can greatly eliminate the blower noise inherent in pneumatic tube systems:
• A remote blower that restricts all blower noise to a location where sound is not objectionable.
• For installations where condensation of moisture particles in the air flow can cause a problem, an outside air intake can
   be incorporated into an Air-Lift Pneumatic System to provide a moisture-free atmosphere.
• Telescoping expansion joists for long, straight runs in variable-temperature conditions.
• Fire dampers - guillotine type - when tubing must penetrate fire walls or floors.

Air-Lift Pneumatic Dispatch Systems can be customized to meet your requirements. For example:
• Stainless steel Send/Receive Stations for food processors, medical facilities, and laboratories.
• Galvanized steel Send/Receive Stations for highly-corrosive environments, such as paper mills and chemical plants.
• Downsend available on all models.
