PM-TK Series Air Compressor
A compact, tank-mounted compressed air system engineered to deliver stable high-pressure air for fibre laser cutting, with the compressor, refrigerated dryer, precision filters and receiver integrated into one coordinated package.
Reliable Compressed Air for Precision Laser Cutting
Fibre laser cutting depends on a consistent assist-gas supply to remove molten material from the kerf and support a stable cutting process. When pressure fluctuates or the air contains excessive moisture, oil aerosol or particles, cut quality may become inconsistent and sensitive laser components can be exposed to unnecessary contamination risk.
The Baldor PM-TK Series combines compressed air generation and treatment in a compact tank-mounted configuration. Positioning the compressor and treatment equipment around the receiver helps reduce the installation footprint while providing the main elements required for a dedicated laser cutting air supply.
This integrated arrangement reduces the need to purchase and coordinate several separate pieces of equipment. It is particularly useful for workshops adding a fibre laser where floor space is limited and a tidy, dedicated high-pressure air station is preferred.
- Stable compressed air delivery up to 16 bar
- Integrated dryer, filtration and air receiver
- Compact layout for space-constrained workshops
- Designed for dedicated fibre laser cutting duties
One Coordinated Package for Laser Cutting Air
Each part of the compressed air system performs a different role. Integrating these elements simplifies system planning and helps deliver cleaner, drier and more stable air to the laser.
High-Pressure Compressor
Generates the airflow and pressure required by the cutting process, with stable delivery helping the laser remove molten material consistently from the cutting zone.
Refrigerated Dryer
Reduces moisture in the compressed air supply. Moisture control supports cutting consistency and helps protect downstream piping, filters and sensitive laser-system components.
Precision Filtration
Filters help reduce oil aerosol, condensate and particles before the air reaches the laser. The appropriate filter arrangement should be confirmed against the machine manufacturer’s air-quality requirement.
Integrated Air Receiver
The receiver provides storage that helps buffer demand changes, reduce rapid cycling and support steadier pressure during cutting operations with varying airflow requirements.
How Compressed Air Conditions Affect the Laser Process
The compressor is part of a wider cutting system. Pressure stability, moisture control and filtration influence how effectively assist air performs at the nozzle and how reliably the air system operates over time.
Pressure and Flow Stability
The cutting machine needs sufficient airflow at the specified pressure while the nozzle is operating. A compressor may reach 16 bar yet still be unsuitable if it cannot sustain the required volume during continuous cutting. Receiver capacity, pipe size, restrictions and pressure loss between the compressor and laser must therefore be considered together. Stable delivery helps maintain a consistent assist-gas jet, supporting slag removal and reducing the likelihood of quality changes caused by fluctuating plant demand.
Moisture and Condensation Control
Atmospheric air always contains water vapour, and compression concentrates that moisture. Without suitable drying and drainage, condensate can form in the receiver or distribution piping and travel towards the laser. A refrigerated dryer helps lower the moisture content, while correctly installed drains remove separated condensate. The required pressure dew point should be checked against the laser manufacturer’s instructions, especially in warm, humid environments or where pipework passes through cooler production areas.
Particle and Oil-Aerosol Filtration
Particles, pipe debris and oil aerosol can increase contamination risk within the air circuit. Precision filters are used in stages to reduce these contaminants before the compressed air reaches sensitive equipment. Filters must be selected for the required flow and pressure, installed in the correct sequence and maintained when pressure drop increases. The target air-quality class should come from the laser supplier because different machines and cutting processes may specify different contaminant limits.
Why Choose a Compact Tank-Mounted Laser Compressor?
A dedicated system allows the pressure, air treatment and storage to be selected around the laser rather than relying on a general plant-air network that may fluctuate with other factory demand.
Reduce Gas Purchasing
For suitable materials and thicknesses, high-pressure compressed air may reduce dependence on purchased nitrogen or oxygen. The commercial benefit depends on operating hours, local gas cost and the required edge finish.
Stable 16-Bar Supply
Consistent high pressure helps evacuate molten slag from the kerf. A dedicated compressor also avoids pressure disturbances caused by other pneumatic equipment connected to a shared factory network.
Cleaner, Drier Air
Integrated drying and filtration help control moisture, oil aerosol and particles before the air reaches the laser, supporting process repeatability and reducing contamination risk.
Simpler Installation
A tank-mounted arrangement uses the receiver as part of the packaged footprint, reducing separate equipment placement, piping interfaces and installation coordination for new workshops or factory upgrades.
Where the PM-TK Series Fits
The PM-TK Series is intended for workshops and metal manufacturers that need a compact, dedicated and treated high-pressure air supply for fibre laser cutting.
Fibre Laser Cutting Machines
Supports fibre laser systems in the approximately 1–20 kW range, subject to the specific airflow and pressure requirements stated by the laser manufacturer.
Sheet-Metal Fabrication
Suitable for job shops and production facilities cutting carbon steel, stainless steel and other compatible sheet materials where compressed-air assist gas meets the required finish.
Automotive Components
Can support repeatable cutting of suitable body, bracket and sheet-metal components where production volume makes onsite compressed air attractive compared with delivered gas.
Information Needed for Correct System Sizing
“16 bar” describes pressure, but pressure alone is not enough to size a compressor. The required airflow changes with nozzle diameter, cutting pressure, laser programme and duty cycle.
Laser and Production Details
Provide the laser brand and model, laser power, nozzle sizes, working pressure, expected cutting hours, simultaneous machines and typical material mix. These details help establish normal and peak air demand.
Air-Quality Requirement
Confirm the manufacturer’s limits for particles, oil and moisture, together with the required pressure dew point. This determines whether the integrated dryer and filters meet the application or require additional treatment.
Site Conditions
Ambient temperature, ventilation, electrical supply, installation space, piping distance and maintenance access can affect equipment performance and should be reviewed before installation.
Operating-Cost Comparison
Compare compressor electricity, maintenance and air-treatment cost against current nitrogen or oxygen usage. Include actual production hours and required cut quality rather than evaluating gas price alone.
PM-TK Laser Cutting Compressor FAQs
What is the Baldor PM-TK Series?
It is a compact, tank-mounted compressed air package developed for fibre laser cutting. The system combines a high-pressure compressor, refrigerated dryer, precision filters and receiver into one coordinated installation.
Why does laser cutting require 16-bar compressed air?
High-pressure assist air helps remove molten material from the cutting kerf. The required pressure and flow depend on the laser, nozzle, material and cutting programme, so the laser manufacturer’s specifications should always be checked.
Can compressed air completely replace nitrogen?
Not for every job. Compressed air can be a practical alternative for suitable materials, thicknesses and finish requirements. Nitrogen may still be preferred where oxide-free edges, colour control or particular downstream processes are critical.
Why are a dryer and filters necessary?
Compression creates heat and concentrates atmospheric moisture and particles. Drying and filtration help prevent water, oil aerosol and contaminants from reaching the laser, supporting reliable operation and consistent cutting.
What laser power range is the PM-TK intended for?
The current product page positions the PM-TK system for fibre laser machines from approximately 1 kW to 20 kW. Final suitability still depends on the individual machine’s pressure and airflow requirement.
Is the system ready for immediate installation?
The integrated tank-mounted package simplifies installation, but the site still requires the correct electrical supply, ventilation, foundation, piping, drainage and safe maintenance access. Commissioning requirements should be confirmed before delivery.
How do I determine the required airflow?
Use the laser manufacturer’s stated consumption and account for nozzle size, pressure, duty cycle, simultaneous cutting and storage. CAMDA can review these details before confirming an equipment recommendation.
What information should I send with my enquiry?
Send the laser brand and model, power rating, required pressure and flow, nozzle sizes, daily operating hours, materials, electrical supply, available space and any air-quality specifications from the machine manufacturer.
