15KW Industrial frequency Integrated Air Compressor
9 month ago15KW Integrated Air Compressor with air dryer
Four-in-one is a short phrase for a specific parts list, and this machine is better described by the list than the label. The 15KW Integrated Air Compressor packages a 15 kW (20 HP) screw compressor, a 20HP refrigerated air dryer, a 600L air tank, four precision filters and four automatic drainers into one cabinet. Each piece is sized to the one next to it, so the buyer does not have to match a compressor to a dryer to a tank and hope the numbers line up.
The compressor stage is the one real choice the buyer makes. Osman builds the same integrated cabinet with either a fixed-speed screw end or a permanent magnet variable-speed end. A plant with steady demand takes the fixed-speed unit and pays less up front; a plant whose demand swings between shifts takes the PM version and saves on power instead. The rest of the package, the dryer, the tank and the filters, stays the same either way.
The standard unit carries a refrigerated dryer, which lowers the dew point and removes most of the water. Where the product cannot tolerate any moisture, a desiccant dryer can be specified in its place, driving the dew point down further for even drier output. That one swap is what moves the machine from general workshop air to air a paint line or a food packer can trust.
The filter train runs four stages, so the air is cleaned in steps instead of being pushed through a single element. Each filter and the dryer have their own automatic drainer, which means the water they collect leaves the system on a timer rather than waiting for someone to remember to open a valve. It is a small detail, but it is the one that keeps the air dry through a full week of unattended running.
The whole unit sits in a footprint of 1080 x 750 x 1030 mm and weighs 380 kg, so it fits a corner that would not hold three separate machines. That is why these units sell into small workshops, temporary production sites and growing factories that need air now but may move it later. One connection on the power side and one on the air side, and the station is running.
Advantages
- Transparent parts list: compressor, dryer, tank, filters and drainers are each itemized, and their sizes are already matched
- Fixed-speed or PM VSD, your choice: the same cabinet can carry a fixed-speed or a permanent magnet screw end, so the drive matches your load
- Dryer upgradeable to desiccant: swap the refrigerated dryer for a desiccant dryer when the product needs lower dew point
- Four-stage filtration with auto-drain: air is cleaned in steps and the collected water drains itself, so the line stays dry unattended
- Saves space and install cost: one cabinet replaces three separate machines and the piping between them
- Easy to relocate: one footprint and two connections mean the unit can move with a changing shop layout
- Tested before dispatch: every unit runs and is commissioned at the factory, which keeps the field failure rate low

Why Choose Us
- Factory direct since 2006: the SA-20A ships from the OSMAN plant in Shenzhen, with about 80% of output going to export markets through a worldwide distributor network
- Integrated units are a core line: the range runs from 10HP to 30HP, so later capacity can be added from the same supplier
- Pre-assembled and pre-tested: every unit ships plumbed, wired and commissioned, so it has already run before it arrives
- Built to your spec: the compressor stage, dryer type and filtration can be tailored to your air quality and load, rather than picked off a fixed sheet
- One quote for the whole system: compressor, dryer, receiver and filters are matched and priced on a single document
- Export terms and stock: sea-freight packing as standard with FOB, CIF or DDP quotes, and consumables held in factory stock
FAQ
Q1: What exactly does the 4-in-1 package include?
A:A 15 kW (20 HP) screw compressor, a 20HP refrigerated dryer, a 0.6 m³ air receiver, four precision filters and four automatic drainers, all inside one cabinet. Every part is sized to the next, so there is nothing to match or plumb on site.
Q2: Can I choose a permanent magnet compressor instead of the fixed-speed unit?
A:Yes. The same integrated cabinet can carry either a fixed-speed screw end or a permanent magnet variable-speed end. Pick fixed speed if your demand is steady and you want the lower purchase price, or pick PM VSD if your load swings and you want to save on electricity.
Q3: Can the refrigerated dryer be upgraded to a desiccant dryer?
A:Yes. The refrigerated dryer is the standard fit. For paint lines, food packaging or any process that needs very dry air, a desiccant dryer can be specified instead, which pushes the dew point down further.
Q4: What do the four precision filters do?
A:They clean the air in stages, removing residual oil, particles and moisture step by step, so the final output is cleaner than air passed through a single element. The filters sit after the dryer in the airflow path.
Q5: What are the automatic drainers for?
A:Each filter and the dryer collect water as they work. The automatic drainers release that water on a timer, so it leaves the system on its own instead of waiting for an operator to open a valve. This is what keeps the air dry through unattended running.
Q6: What are the rated specifications?
A:15 kW (20 HP), 380 V three-phase 50 Hz, working pressure 0.8 to 1.2 MPa, free air delivery 2.6 to 1.8 m³/min, direct drive, air cooled. The unit measures 1080 x 750 x 1030 mm and weighs 380 kg. Voltage can be built to suit other supplies.
