This document discusses pneumatic tube systems (PTS), which use compressed air to transport carriers holding materials through a network of tubes. It describes the key components of PTS including blowers, carriers, diverters, tubes, and receiving areas. Point-to-point, semi-automatic, and fully automatic systems are presented. Advantages are speed and reduced delivery time, but disadvantages include noise and heat from friction. PTS have applications in hospitals, banks, industries, and post offices to transport items like medicines, cash, materials, and letters.

4.  A system that uses compressed air as a working
medium for transmission is known as
Pneumatic System.

5.  A Pneumatic Tube System (PTS) is a System in
which Carriers are sent through a network of
tubes by compressed air or by vacuum.

6.  Pneumatic Tube System has a speed of 6-8m/s
 Saves time
 Allow your staff to concentrate on more
important work

12.  The Driving force of Pneumatic tube system is
blower.
 Due to the air flow the carrier will start to move
in the transport.

13.  Carrier are the containers that hold materials
and goods as they move through a tube system.
 Size of the carrier is 150cm diagram and 20-30
cm long.

14.  Diverters act as a switching station that allows a
carrier to travel to its destination in the most
direct path set up by the diverters.

15.  The Carrier move through especially fabricated
gray plastic pipe.

16.  The arrival signals announce the arriving carrier
to the receiver

17.  The receiving basket is used for the soft
reception of arriving carriers.

18.  Fire protection sleeves will assist in compliance
with fire protection codes and standards. By
sealing hermetically the areas of increased
concern as specified, PVC tubing may be an
alternative.

19.  The Area where the carriers are exchanged.

21.  We take the transport process from station 3 to
station 2 as example.
 Firstly, the carrier enters into the tube system
through the station 5.
 Then Diverter 1 is set at the left branch and
blower unit 1 generates suction by partial
vacuum. Soon the carrier arrives in point A.
 Diverter 1turns to the middle branch and
blower unit 1 produces compressed air to pull
the carrier to point B.

22.  The carrier gets into Top slot 1 of transfer
center by gravity and then falls into the car,
which can move between the bottom slots back
and forth.
 With the help of the car , the carrier arrives at
point D.
 Blower unit 2 produces compressed air to push
the carrier to station.

23.  Decreased material delivery time.
 Carrier are transported at speed of 6-8 m/s.
 Can transport up to 3-7kg material.
 Less prone to human error.
 Lesser staff requirement.
 Reduced maintenance cost.

24.  Heat is generated due to friction.
 Bends in system cause deceleration.
 Noise is generated.

25.  In hospitals, for transporting test tubes or
tissue jars, medicines and blood products.
 In banks for the purchase and removal of cash
and valuable.
 Industries for sending raw materials.
 In post offices for sending letters.

26.  The pneumatic tube system is logistics
transportations system.
 This system uses pneumatics as power , which
is controlled by computer.
 This system could implement the task to carry
goods between systems or within system.
