Increase air pressure where you need it.
Maximator air amplifiers are air-driven pressure boosters designed to increase plant or shop air pressure at the point of use. They provide higher-pressure air for workstations, pneumatic machinery, tools and other applications when available air pressure is insufficient.
Using the same compressed-air source for both operation and amplification, Maximator air amplifiers require no electrical power. Models are available in single-stage, single-acting and single-stage, double-acting configurations to address a range of pressure and flow requirements, with air pressures from 30 psi to 4,350 psi.
Why Air Amplifiers?
Increasing the pressure of an entire compressed-air system is not always practical when only one machine, workstation or process requires additional pressure. Maximator air amplifiers provide a point-of-use solution by increasing the available air pressure at the application.
Air amplifiers are well suited for applications that require intermittent higher-pressure air, including pneumatic equipment, air-operated tools, cylinders and injection molding equipment.

Which Air Amplifier Is Right for Your Application?
The appropriate air amplifier depends on several application requirements, including:
• Available supply pressure
• Required outlet pressure
• Required flow
• Pressure ratio
• Single- or double-acting operation
• Application requirements
Maximator US can help you select the appropriate air amplifier based on your pressure, flow and application requirements.
How does an Air Amplifier Work?
Maximator air amplifiers use incoming compressed air to provide both the power required to operate the amplifier and the air being amplified. The amplifier increases air pressure through the relationship between the areas of its pistons.
On DLA models, a larger air piston drives a smaller piston to generate higher pressure. On PLV models, two fixed-area pistons drive a piston of the same area.
Tappet valves at the end of each stroke provide an air-shift signal to a four-way spool valve. The spool valve directs drive air to alternate sides of the drive piston or pistons, producing the reciprocating action of the amplifier. Drive air is exhausted while amplified air is delivered to the outlet.
Once the desired end pressure is reached, the amplifier stalls and stops cycling. If pressure drops approximately 1% from the stall pressure, the amplifier automatically restarts.
Understanding Air Amplifier Pressure Ratios
Maximator air amplifiers are available in pressure ratios of 2:1, 4:1, 5:1, 15:1 and 30:1, depending on the model. The pressure ratio is determined by the piston-area relationship within the amplifier.
The appropriate pressure ratio depends on the available supply pressure and the required outlet pressure. Flow requirements must also be considered when selecting an amplifier.
For example, a higher-pressure ratio can provide greater pressure amplification from a given supply pressure, while the required flow and operating conditions still determine which amplifier is appropriate for the application.
Maximator air amplifiers are available with maximum rated pressures from 300 psi to 4,350 psi, depending on model.

Air Supply Requirements
Proper air quality is important for reliable air amplifier operation. Maximator recommends filtering the air supplied to the amplifier to 5–40 µm and maintaining a dew point between 0°F and 50°F.
Very moist air can wash out the lubricant used on the seals, while very dry air may require a Dry Air Spool.
Maximum air drive pressure: 145 psi
For applications involving very low dew-point air or cold operating environments, Maximator offers a Dry Air Spool option.

Air Amplifiers Frequently Asked Questions
An air amplifier is an air-driven pressure booster that increases the pressure of an existing compressed-air supply. Air amplifiers are designed for point-of-use applications where additional air pressure is required for pneumatic equipment, tools, cylinders, machinery or other processes.
An air amplifier uses incoming compressed air to provide both the power required to operate the amplifier and the air being amplified. The pressure increase is generated through the relationship between the areas of the amplifier's pistons. A four-way spool valve controls the reciprocating operation of the amplifier.
Air amplifiers are available in 2:1, 4:1, 5:1, 15:1 and 30:1 pressure ratios, depending on the model. This range allows an amplifier to be selected based on the available supply pressure and required outlet pressure.
Maximum rated pressure varies by model. The Maximator air amplifier range includes models with maximum rated pressures from 300 psi to 4,350 psi. The appropriate model depends on the available supply pressure, required outlet pressure, flow requirements and application.
Single-stage, single-acting and single-stage, double-acting air amplifiers are available for different pressure and flow requirements. Double-acting models are intended for applications requiring both increased pressure and higher flow.
No. Air amplifiers use incoming compressed air to provide both the power required to operate the amplifier and the air being amplified.
Selecting an air amplifier depends on the available supply pressure, required outlet pressure, flow requirements, pressure ratio and application requirements. Multiple models and configurations are available to accommodate different pressure and flow requirements. Maximator US can help you select the appropriate air amplifier for your application.
Maximator recommends filtering the air supplied to the amplifier to 5–40 µm and maintaining a dew point between 0°F and 50°F. Very moist air can wash out seal lubricant, while very dry air may require a Dry Air Spool.
When the desired end pressure is reached, the air amplifier stalls and stops cycling. It automatically restarts when a drop of approximately 1% from the stall pressure is detected.
