High Pressure Combi Booster Air Compressor

Selecting a booster is a highly technical process that centers on two key parameters: pressure (required operating force) and flow rate (air supply capacity per unit of time).

It is recommended to follow these steps:

• Define requirements: Calculate the total air consumption of all high-pressure air usage points on the production line and determine the maximum required operating pressure. For example, in PET bottle blowing, thicker walls, more complex shapes, or larger bottle sizes generally require higher pressure.
• Consider environmental factors: The factory's altitude, ambient temperature, and humidity affect the compressor's actual air output efficiency; these factors must be accounted for during selection.
• Evaluate layout options: Boosters can be arranged centrally in a compressor room or distributed near the points of use. A "hybrid layout" is currently recommended-where the main compressor room supplies air and silent-type boosters are installed next to the points of use-as this eliminates the cost of laying expensive high-pressure piping.

They are widely used in specific industrial applications requiring high-pressure or ultra-high-pressure gas sources:

• PET bottle manufacturing: Blow molding of beverage and edible oil bottles (typically requiring a medium-to-high pressure gas source of 30–40 bar).
• Laser cutting: High-pressure oxygen or nitrogen assist for high-speed, oxidation-free cutting of metal sheets.
• Pressure and leak testing: High-pressure hydrostatic or pneumatic strength testing for valves, pipelines, pressure vessels, etc.
• National defense, aerospace, and scientific research: High-pressure gas cylinder filling, specialized gas supply, etc.

• Check for leaks regularly: Closely monitor intake and exhaust piping, connections, and valve assemblies for air leaks, as these can significantly reduce system energy efficiency.
• Consumable replacement: Periodically replace the air filter elements at the intake and within the unit itself.
• Lubrication management: For oil-lubricated models, regularly check the lubricant level and quality, and replace the oil with approved compressor-specific lubricant at the recommended intervals.
• Safety valve and condensate drainage: Periodically test the sensitivity of the safety valves and promptly drain condensate from the air-water separators at each stage.

Since high-pressure reciprocating piston boosters generate mechanical and airflow pulsations during the compression stroke, methods to control vibration and noise include:

• Foundation vibration isolation: Installing specialized rubber vibration pads or spring isolators at the base of the unit to prevent rigid connections from causing ground resonance.
• Precision dynamic balancing: Ensuring high precision in the machining and assembly of moving parts such as the crankshaft, connecting rods, and pistons.
• Silencers and sound-insulating enclosures: Installing high-efficiency silencers at the air intake and equipping the entire unit with a fully enclosed sound-insulating housing lined with sound-absorbing material.
