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.

Each model number is made up of “BB” followed by three numbers separated
by dashes. The first number indicates discharge pipe diameter, the second
number indicates tank diameter, and the third number indicates tank length
(all in inches). For example, model BB4-12-28 has a nominal discharge
diameter of 4 in. (102 mm), a tank diameter of 12 in. (305 mm), and a tank
length of 28 in. (711 mm).
Specifications Nine different Martin®XHV Air Cannon models are available. Each model is
listed below. The volume of air held in the tank increases with pressure.
Air cannon dimensions, tank volume, fill times, and discharge times are
provided in Appendix A.
Required
accessories
This manual includes instructions for installing accessories required for
Martin®XHV Air Cannons to be fully operational (see Figure 4). The
following accessories can be ordered from Martin Engineering and shipped
separately from air cannons (see “Part Numbers”):
• Quick exhaust valve (A).
• Air control components: manual valve (B) or electrical solenoid valve (C),
air filter (D), air regulator (E), air lubricator (F), lockout ball valve (G), and
check valve (H).

Before Installing Air Cannon
IMPORTANT
The delivery service is responsible for damage occurring in
transit. Martin Engineering CANNOT enter claims for
damages. Contact your transportation agent for more
information.
1. Inspect shipping container for damage. Report damage to delivery service
immediately and fill out delivery service’s claim form. Keep any damaged
goods subject to examination.
2. Remove air cannon from shipping container. Equipment in container
should include the following:
• Air cannon, relief valve, and pipe nipple.
• Air Blast Warning Label, P/N 31913.
• Lockout Valve Warning Tag, P/N 35146.
3. If you ordered accessories from Martin Engineering, remove from
shipping container. Equipment in container may include the following:
• Quick exhaust valve.
• Air control components: manual valve or electrical solenoid valve, air
filter/regulator/lubricator, air supply line, lockout ball valve, and check
valve.
4. If anything is missing, contact Martin Engineering or representative.
WARNING
!
Before installing air cannon, lock out/tag out any equipment
that is loading or unloading material from the storage vessel.
5. Turn off and lock out/tag out energy source to accessory equipment
according to ANSI standards (see “References”).
WARNING
!
If equipment will be installed in an enclosed area, test gas level
or dust content before using a cutting torch or welding. Using
a cutting torch or welding in an area with gas or dust may
cause an explosion.
6. If using a cutting torch or welding, test atmosphere for gas level or dust
content.
Before Installation

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.
8. If you need to know air cannon maximum force output for your
application, call Martin Engineering.
