Actual filling times depend on the reservoir's starting pressure, capacity, selected final pressure and operating conditions.

The defining feature of the PAC ECO Silent is its exceptionally low operating noise. Umarex rates the compressor at approximately 60 dB, making it significantly quieter than the other models in the PAC range.

For comparison, the PAC 900 operates at approximately 78 dB, the PAC 400 at 80 dB and the PAC 1100 and PAC 1400 at approximately 72 dB.

Because the decibel scale is logarithmic, these differences are meaningful. The PAC ECO Silent offers a considerably quieter operating experience than faster conventional PCP compressors.

This makes it particularly attractive for home workshops, garages and other suitable environments where excessive compressor noise would be undesirable.

The trade-off is filling speed. The PAC ECO Silent takes substantially longer to fill a PCP reservoir than the higher-performance PAC models.

Although designed for reduced noise, the compressor is not completely silent. Actual perceived noise depends on the surrounding environment, installation surface and distance from the unit.

The PAC ECO Silent operates from a suitable 230V mains electricity supply using its included separate power supply unit.

Unlike the battery-powered PAC 400 or the dual-power PAC 1100 and PAC 1400, the PAC ECO Silent does not offer rechargeable battery or 12V vehicle-powered operation.

This makes it particularly well suited to PCP owners who normally refill their air rifles at home or in a workshop with reliable access to mains electricity.

Its compact upright construction occupies relatively little bench or floor space, while its approximately 6.3 kg weight makes it practical to reposition when required.

Use the supplied power supply unit and manufacturer-approved mains connection equipment. Never substitute an incompatible power supply.

Position the compressor on a stable, dry surface with adequate ventilation, and keep all electrical equipment away from moisture.

The PAC ECO Silent is designed for shooters who value quiet, convenient PCP filling rather than maximum charging speed.

With a maximum output pressure of 300 bar (4,350 psi), the compressor is suitable for compatible PCP airgun reservoirs approved for filling at pressures up to this level.

Umarex specifies a reference filling time of approximately 72 minutes for a 0.2-litre reservoir at 190 bar.

This is considerably slower than the PAC 900, PAC 1100 and PAC 1400, but the PAC ECO Silent offers substantially reduced operating noise in return.

The manufacturer's published comparison table specifies a maximum reservoir volume of less than 1 litre.

This makes the compressor most suitable for individual PCP airguns and smaller reservoirs rather than large external compressed-air cylinders.

Actual filling times depend on the reservoir's starting pressure, capacity, target pressure and operating conditions.

Users who regularly refill larger reservoirs or need faster charging should consider the PAC 900, PAC 1100 or PAC 1400.

Always follow the maximum filling pressure specified by the airgun or reservoir manufacturer. Never exceed the reservoir's pressure rating.

The PAC ECO Silent features an adjustable automatic shut-off system, allowing 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 digital display provides a clear interface for selecting and monitoring the required pressure.

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

For example, an air rifle rated for 200 bar must not be filled to 300 bar simply because the compressor is capable of reaching that pressure.

Always confirm the correct target pressure before starting and monitor the compressor throughout operation.

The automatic shut-off system does not replace the need for correct filling procedures and supervision.

The Umarex PAC ECO Silent 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 incorporates a moisture separator with an accessible drainage arrangement, helping manage condensation produced during high-pressure air compression.

Follow the manufacturer's instructions for draining accumulated moisture and releasing residual pressure safely.

Oil-free operation and the absence of external water cooling do not mean that compressed air is guaranteed to be completely free from atmospheric moisture.

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

Regularly inspect the filling hose, seals, connections and electrical equipment for signs of wear, damage or leaks.

Always follow the supplied Umarex operating instructions for maintenance, cooling intervals and safe operation.

The PAC ECO Silent is designed for filling compatible pre-charged pneumatic airguns and suitable high-pressure compressed-air reservoirs within its 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, helping accommodate a wide range of popular PCP filling systems.

Some PCP airguns use manufacturer-specific filling probes or alternative connection types. These may require an additional compatible adapter.

Before filling, check that the reservoir is approved for high-pressure compressed air, that the connection is correctly fitted and that the selected pressure does not exceed the reservoir manufacturer's maximum filling pressure.

Do not use the compressor to fill reservoirs outside its specified capacity or pressure limits.

If you are unsure whether the PAC ECO Silent is suitable for your air rifle, contact Bamfords Online for compatibility advice.

The PAC ECO Silent is an excellent choice for PCP owners who want to fill their air rifles at home while keeping operating noise to a minimum.

It is particularly suitable for:

• Shooters who prioritise quiet compressor operation
• Home workshop and garage use
• Owners who refill smaller PCP reservoirs occasionally
• Users who prefer a compact upright compressor
• Those who do not require battery or vehicle-powered operation
• PCP owners who are comfortable with longer filling times

For shooters who regularly refill larger reservoirs or need faster charging, the PAC 900, PAC 1100 or PAC 1400 may be more suitable.

For users who need a compressor that operates away from mains electricity, the battery-powered PAC 400 or dual-power PAC 1400 offers greater flexibility.

Always read the supplied Umarex operating instructions before using the PAC ECO Silent. 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, power supply, mains cable, seals and reservoir for damage.
• Connect the correct approved filling adapter securely.
• Connect the supplied power supply unit in accordance with the manufacturer's instructions.
• Connect the power supply to a suitable 230V mains electricity supply.
• Set the required 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 and moisture-drainage procedures 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 attempt to fill a damaged or unsuitable reservoir.
