One of the main advantages of the Umarex PAC 1400 is its flexible power supply. Unlike compressors that rely exclusively on a mains socket, this model can operate using either 230V electricity or its rechargeable lithium-ion battery system.

For stationary filling at home or in the workshop, the compressor can be connected to a suitable 230V mains supply using the supplied power equipment.

For mobile use, the compressor operates using two 18V 5.2Ah lithium-ion batteries. Both batteries and their chargers are included in the standard manufacturer package, allowing the compressor to be used away from a mains connection once the batteries are charged.

The battery arrangement is compatible with the Makita battery standard. An optional adapter set is available for selected batteries from Black & Decker, Bosch, Einhell, Metabo and Parkside. These additional adapters are not included as standard.

Always use the power equipment and batteries specified or approved by Umarex. Do not connect mains and battery power simultaneously.

Please note that the standard mains equipment is supplied with an EU plug. A suitable UK adapter is required for connection to a UK three-pin socket unless a UK-compatible arrangement has been supplied separately.

The PAC 1400 is designed for shooters who need faster PCP filling without sacrificing portability.

With a maximum output pressure of 300 bar (4,350 psi), it can refill a wide range of compatible PCP airgun reservoirs, including those designed for higher-pressure charging.

Umarex specifies a reference filling time of approximately 4 minutes and 5 seconds for a 0.2-litre reservoir at 190 bar. This makes the PAC 1400 particularly attractive to shooters who fill their airguns regularly or use larger-capacity PCP reservoirs.

The compressor supports compatible filling volumes up to 3 litres in a single filling process, providing greater flexibility than smaller portable compressors designed primarily for individual airgun cylinders.

Actual filling times vary according to the starting pressure, reservoir volume, selected pressure and operating conditions. The manufacturer's reference time should not be treated as a guaranteed result for every fill.

Only fill suitable compressed-air reservoirs that are approved for the intended pressure. The compressor's maximum output does not override the pressure limit marked on your airgun or cylinder.

The PAC 1400 features an adjustable automatic shut-off system, allowing the required filling pressure to be selected in precise 1-bar increments.

Once the selected pressure has been reached, the compressor automatically stops the filling process, helping provide consistent and controlled operation.

The clear digital display allows the user to monitor the relevant filling parameters during operation.

This is particularly useful for shooters who own multiple PCP airguns with different recommended filling pressures.

Always select the correct pressure for the specific airgun or reservoir being filled. Never exceed its manufacturer-approved maximum pressure, even if the compressor is capable of reaching a higher figure.

The automatic shut-off system is a useful safeguard, but the compressor should still be supervised throughout the filling process.

The Umarex PAC 1400 is designed for oil-free and water-free operation, reducing the preparation and routine maintenance associated with traditional high-pressure compressors.

There is no requirement to add compressor oil or connect a separate external water-cooling container before use.

An integrated overheat protection system helps protect the compressor if operating temperatures become excessive.

The unit also features an easily replaceable filter sponge, allowing straightforward routine maintenance.

Keep the compressor's ventilation openings unobstructed and ensure that it is positioned on a stable surface with sufficient airflow during use.

Oil-free and water-free operation describes the compressor's lubrication and cooling arrangements. It does not mean that atmospheric moisture is completely eliminated from the compressed air.

Inspect the filling hose, seals, connections and filtration components regularly, and follow the supplied Umarex instructions for servicing, pressure release and maintenance.

The PAC 1400 is designed for filling compatible pre-charged pneumatic airguns and suitable high-pressure compressed-air reservoirs.

The supplied high-pressure filling hose uses a Foster connection, a common fitting arrangement for PCP shooting equipment.

Adapters for 1/8", M10 and M10x1 connections are included, helping accommodate a wide range of popular PCP filling systems.

Some air rifles use proprietary filling probes or alternative connectors. These may require an additional compatible adapter.

Before filling, confirm that the reservoir is suitable for compressed air, that the connection is correctly fitted and that the selected pressure does not exceed the reservoir's permitted working pressure.

If you are unsure whether the PAC 1400 will connect to your air rifle, contact Bamfords Online for assistance before ordering.

With its rechargeable battery system and compact design, the PAC 1400 offers convenient filling away from a fixed mains supply.

This makes it useful for shooting ranges, outdoor practice locations and other appropriate settings where access to electricity is limited.

The standard package includes two 18V 5.2Ah lithium-ion batteries and two chargers.

Actual battery runtime and the number of fills available per charge depend on the size of the air reservoir, its starting pressure, the selected target pressure, ambient conditions and battery condition.

Umarex does not provide a single guaranteed number of fills per charge that applies to every PCP airgun. For this reason, users should plan battery capacity around their particular filling requirements.

Allow the batteries to cool as required before charging and follow the supplied instructions for safe charging, storage and transportation.

Always read the supplied Umarex operating instructions before using the PAC 1400. The following is a general overview and does not replace the manufacturer's procedure.

• Position the compressor on a stable, dry surface with adequate ventilation.
• Inspect the filling hose, seals and reservoir for damage.
• Choose either the appropriate mains supply or the approved battery power arrangement.
• Never connect mains and battery power simultaneously.
• Attach the correct compatible filling connector securely.
• Set the required pressure according to the airgun or reservoir manufacturer's instructions.
• Start the filling process using the compressor's controls.
• Monitor the pressure, temperature and operating condition throughout the fill.
• Allow the compressor to stop when the selected pressure is reached.
• Follow the manufacturer's pressure-release procedure before disconnecting the filling hose.
• Inspect and maintain the filter and other serviceable components as instructed.

Never leave the compressor operating unattended, disconnect a pressurised hose or attempt to fill a damaged or unsuitable reservoir.
