One of the main advantages of the PAC 1100 is its dual power capability. The compressor can operate from a suitable 230V mains electricity supply or from a compatible 12V vehicle power source.

For home use, mains operation provides a convenient solution for filling PCP air rifles in a workshop, garage or other suitable location.

When mains electricity is unavailable, the supplied 12V vehicle connection cable set allows the compressor to be powered from an appropriate vehicle electrical supply, provided the vehicle and electrical system meet the compressor manufacturer's requirements.

This makes the PAC 1100 particularly attractive to shooters who want the flexibility to refill their PCP equipment at home and while travelling.

The PAC 1100 does not contain a rechargeable battery and cannot operate independently of an external electrical supply.

Always use the supplied or manufacturer-approved cables and follow the operating instructions regarding power connections, current requirements and safe vehicle operation.

Do not assume that a standard 12V accessory socket is suitable. Use only the vehicle connection arrangement specified by Umarex.

The PAC 1100 is designed to deliver rapid high-pressure filling for compatible PCP airguns, with a maximum output pressure of 320 bar (4,640 psi).

Umarex lists a reference filling time of approximately 4 minutes and 48 seconds for a 0.2-litre reservoir at 190 bar.

Its maximum supported reservoir volume of 3 litres gives it greater capacity than the PAC 400, PAC 900 and PAC ECO Silent models.

This makes it suitable for a broader range of compatible PCP reservoirs, including certain larger airgun cylinders, provided the reservoir falls within the manufacturer's specified limits.

The PAC 1100 is particularly useful for shooters who refill their rifles regularly and want faster performance than smaller entry-level compressors.

Actual filling times depend on reservoir volume, starting pressure, target pressure, ambient conditions and the electrical power supply used.

Always follow the maximum filling pressure specified by the airgun or reservoir manufacturer. A reservoir rated to 200 bar must never be filled to 320 bar.

The PAC 1100 features an adjustable automatic shut-off system that allows the desired filling pressure to be selected in precise 1-bar increments.

Once the selected pressure is reached, the compressor automatically stops the filling process.

The integrated digital display allows the user to select and monitor the required pressure, helping provide a controlled filling process.

This is particularly useful for owners of multiple PCP airguns with different recommended charging pressures.

Always check the correct pressure for the reservoir before starting and monitor the compressor throughout operation.

The automatic shut-off feature does not remove the need to follow the manufacturer's operating instructions or supervise the filling process.

The PAC 1100 features an oil-free compressor design, eliminating the need for routine compressor oil changes.

It also operates without an external water-cooling tank or pump, helping simplify preparation and routine use.

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

The compressor is fitted with a replaceable sponge air filter, which should be inspected and maintained in accordance with the manufacturer's instructions.

Keep ventilation openings unobstructed and operate the compressor on a stable, dry surface with adequate airflow.

Oil-free operation does not mean that the compressed air is guaranteed to be free from atmospheric moisture. Follow the manufacturer's instructions for any moisture management or filtration requirements.

Regularly inspect the filling hose, seals, fittings and electrical cables for signs of wear or damage.

Never operate the compressor with damaged components or attempt unauthorised repairs.

The PAC 1100 is designed for filling compatible pre-charged pneumatic airguns and approved compressed-air reservoirs within the compressor's specified pressure and capacity limits.

The supplied high-pressure filling hose uses a Foster connection, a widely used fitting type for PCP airgun charging equipment.

Adapters for 1/8", M10 and M10x1 connections are included.

Some PCP airguns use manufacturer-specific filling probes or other connection types, which may require an additional compatible adapter.

Before filling, confirm that the reservoir is suitable for high-pressure compressed air, that all fittings are correctly connected and that the selected pressure is within the reservoir manufacturer's limit.

Never attempt to fill an unsuitable, damaged or unapproved pressure vessel.

With a compact design and approximately 8.5 kg weight, the PAC 1100 is suitable for users who want a compressor that can be moved between a home workshop and other suitable filling locations.

The 12V vehicle power option adds useful flexibility when a mains supply is unavailable.

Umarex rates the PAC 1100 at approximately 72 dB, making it quieter than the PAC 900 and PAC 400 according to their published figures, although it is not as quiet as the PAC ECO Silent.

For users who want a balance of filling speed, reservoir capacity and portable power options, the PAC 1100 is a particularly versatile choice.

Ensure the compressor is used in a suitable environment with adequate ventilation, stable positioning and appropriate electrical connections.

Always read the supplied Umarex operating instructions before using the PAC 1100. The following is a general overview and does not replace the manufacturer's procedure.

• Position the compressor on a firm, level and dry surface with adequate ventilation.
• Inspect the filling hose, electrical cables, seals and reservoir for damage.
• Connect the appropriate filling adapter securely to the compatible PCP reservoir.
• Connect the compressor to a suitable 230V mains supply or approved 12V vehicle power source.
• Set the required filling pressure according to the airgun or reservoir manufacturer's instructions.
• Start the filling process using the compressor 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 compressor and filling accessories as instructed.

Never leave the compressor operating unattended, disconnect a pressurised hose or exceed the pressure rating of the reservoir.
