Lowdoller Motorsports | Aluminium CO2 Bottle - 2.5LB

Lowdoller Motorsports 2.5LB Aluminum CO2 Bottle

LDM Aluminum CO2 Bottle – 2.5LB

Supply your race-car pneumatic systems with a compact and lightweight Lowdoller Motorsports 2.5LB Aluminum CO2 Bottle, designed for drag racing and motorsport applications where reliable compressed-gas storage is required.

Ideal for air shifters, boost-control systems and other CO2-operated race-car components, this bottle provides a practical balance between gas capacity, compact dimensions and low weight.

The aluminium construction keeps unnecessary mass to a minimum, while the supplied brass valve and CGA 320 nipple provide a durable connection point for compatible regulators and CO2 control systems.

A built-in 3,000 psi blow-off port provides an important pressure-safety feature for demanding motorsport use.

Ideal for Race-Car Pneumatics

CO2 is widely used in drag racing because it provides a compact and consistent compressed-gas source for multiple pneumatic systems.

A 2.5LB bottle provides useful capacity without taking up excessive space, making it well suited to tightly packaged competition vehicles.

Depending on the vehicle configuration, a single CO2 supply may be used to support systems such as:

• Air shifters
• Boost-control solenoids
• Pneumatic wastegates
• Transmission controls
• Other compatible race-car pneumatic devices

CGA 320 Valve Connection

The supplied brass valve uses a CGA 320 nipple, a common CO2 connection format that allows the bottle to be paired with compatible motorsport regulators and control hardware.

Lowdoller also offers an electric CO2 bottle solenoid/regulator separately, providing an option for racers building a complete electronically controlled CO2 system.

Important Installation Notes

The bottle should always be securely mounted using an appropriate bottle bracket or retention system suitable for motorsport use.

Ensure all regulators, fittings, hoses and solenoids are rated for the pressures associated with CO2 systems.

CO2 bottles should only be filled, inspected and serviced by appropriately equipped personnel. Never exceed the bottle or connected component pressure ratings.
