Introduction
General The Martin®XHV Air Cannons are pneumatic, bulk material-moving systems
that quickly release compressed air into a storage vessel to restore flow to
material that is clinging (A), bridging (B), rat-holing (C), or arching (D) (see
Figure 1). This manual provides instructions for installing cannons on steel
structures only. For installations on other structures, call Martin Engineering
or a representative.
Figure 1. Restricted Material
Operation The Martin®XHV Air Cannon System consists of one or more air cannons
mounted on a storage vessel. The air cannon charges when the tank is filled
with plant compressed air or nitrogen between 40 psi (2.76 bar) and 120 psi
(8.27 bar) (A, Figure 2) that is controlled by a 3-way normally open solenoid
valve. Air fed through the valve body-mounted quick exhaust valve (QEV)
passes through the piston and into the tank (B). When tank pressure equals
line pressure, airflow is static and the cannon is ready to discharge (C). By
activating the solenoid valve, the air supply is shut off and the air line between
the QEV and solenoid is emptied. This allows the QEV to quickly release the
pressure holding the piston. The piston is instantly forced back by the pressure
stored in the tank which then exits through the discharge pipe, releasing the
energized air pressure stored in the tank. This blast of air is directed through
the discharge pipe and into the storage vessel (D).
Air cannon
materials
The air cannon tank is manufactured to American Society of Mechanical
Engineers (ASME) Code Rules, Section VIII, Division 1. It is National Board
registered, and is pressure vessel quality (PVQ). After the tank is welded,
paint is applied inside the tank to prevent rust and corrosion. Never weld
tank. Welding will melt paint and violate ASME coding.

Before Installation

Martin Engineering M3404-05/12 6Martin®XHV Air Cannons
CAUTION
!
When blasting into closed storage vessel, exhaust vents must
be considered to prevent internal vessel air pressure from
increasing to point where it may damage vessel.
7. When blasting into closed storage vessel, consider exhaust vents to
prevent internal vessel air pressure from increasing to point where it may
damage vessel. Calculate temporary vessel pressure after air cannon
discharge with the following equation:
If calculated pressure is greater than 0.5 psi (.034 bar), install exhaust
vents to avoid damage to storage vessel. Observe local and state codes,
which may specify limits less than 0.5 psi (.034 bar).
IMPORTANT
Air cannon force output can vary depending on inlet pressure,
discharge opening size, structure size, material in structure,
and other factors. To determine maximum force output values
for your application, call Martin Engineering.

WARNING
!
If air cannon is mounted more than 6 in. (152 mm) above
ground, install restraining cable to secure air cannon to
storage vessel. Without restraining cable, air cannon could fall
and cause injury.
Do not use restraining cable to mount air cannon to storage
vessel wall. Purpose of restraining cable is to keep air cannon
from falling should it come loose from vessel wall, not as
primary means of securing air cannon to wall.
CAUTION
!
Do not use angle iron or support ring to secure air cannon
rigidly to storage vessel. If restrained too rigidly, tank cannot
flex and cannon can fail.
1. Weld D-ring (A, Figure 12) onto storage vessel (B) with 1/4-in. (6-mm)
field weld.

IMPORTANT
Read entire section before beginning work.
CAUTION
!
When pressure in the storage vessel is 4 psi (0.28 bar) or more,
apply equal or greater pressure to the air cannon inlet.
Absence of inlet pressure will allow material in the storage
vessel to enter the air cannon and contaminate the valve body
and tank.
Installing manual valves and electrical solenoid valves
Materials Required:

WARNING
!
Make sure exhaust port on quick exhaust valve is pointed
downward so that dirt cannot enter, and exhaust port is not
directed at personnel. Martin Engineering recommends
installing a 90° street elbow on quick exhaust valve exhaust
port and on manual or electrical solenoid valve exhaust ports
to prevent dirt from entering.
3. If using optional 90° street elbow (C) for quick exhaust valve, thread it
into quick exhaust valve exhaust port (D).
4. Thread quick exhaust valve outlet port (with exhaust port pointed down)
onto hex nipple and tighten.
IMPORTANT
Manual valves or electrical solenoid valves distributed by
Martin Engineering, which are made especially for this air
cannon, are recommended. Substitute valves may not work as
effectively.
Use any length pipe to connect air filter/regulator/lubricator
to check valve. Use 1/2-in. pipe only. Locate manual valve or
electrical solenoid valve within 15 ft (4-1/2 m) of air cannon.
5. Choose location for manual 3-way valve (E, Figure 13) or electrical
solenoid valve (E, Figure 14).
6. Install bushing (F, Figure 13 or 14) into quick exhaust valve inlet port.
7. Connect manual 3-way valve or electrical solenoid valve outlet port to
bushing/quick exhaust valve inlet port with no more than 15 ft (4-1/2 m)
of 1/2-in. pipe (G).
8. Install 90° street elbow (H) for manual 3-way valve or electrical solenoid
valve into valve exhaust port.
NOTE
Look at arrow on side of FRL, check valve, and lockout ball
valve to make sure flow is correct.
9. Connect air filter/regulator/lubricator (J) and manual 3-way valve or
electrical solenoid inlet port with desired length 1/2-in. pipe.
IMPORTANT
OSHA requires installation of a lockout ball valve (see
“References”).
10. Connect lockout ball valve (K) to air filter/regulator/lubricator with
desired length 1/2-in. pipe. Look at arrow on side of ball valve to make
sure flow is correct.
11. Fill lubricator with Martin®High-Temperature Oil. Set lubricator to
release one drop per hour.
12. Connect check valve (L) to lockout ball valve with desired length 1/2-in.
pipe. Look at symbol on side of check valve to make sure flow is correct.

IMPORTANT
For electrical solenoid valve installations, design and wire
electrical solenoid controls according to NEC Handbook.
Electrical push buttons, timers, and programmable
controllers are available through Martin Engineering.
13. For electrical solenoid valve installations, if using electrical solenoid
controller, install according to instructions provided with controller.
WARNING
!
Do not exceed 125 psi (8.62 bar) maximum working pressure
or pressure relief valve will open. Minimum recommended
pressure for most applications is 80 psi (5.52 bar) but lower
pressures can be used. Make sure air supply is filtered and
regulated.
NOTE
Pressure relief valves of up to 150 psi are available from
Martin Engineering. Consult the Maximum Allowable
Working Pressure (MAWP) on tank's name plate before
substituting a different pressure relief valve. Never use a
pressure relief valve with a set pressure that is higher than the
MAWP of the tank.
WARNING
!
Pressure relief valve may relieve at any point between 90%
and 100% of set pressure. Exceeding MAWP can cause tank to
rupture.
14. Connect air supply (M) to check valve.
15. Anchor all pipes and wires to prohibit movement.
16. Operate air cannon as described under “After Installing Air Cannon.”
