Split-Type Energy Saving Oil-Free Scroll Air Compressor
The split-type architecture isolates mechanical vibration and heat dissipation, enabling direct placement inside cleanrooms, laboratories, or production floors without acoustic enclosures. Dual or multi-scroll air ends operate in parallel sequences, matching fluctuating air demand via staged load-unload control to prevent energy waste during low-load intervals.

Split-Type Architecture & Layout
Independent Footprint: Decouples the compression module and air receiver tank to reduce concentrated floor loading and fit narrow utility corridors.
Vibration Isolation: Multi-stage elastomeric shock absorbers prevent dynamic scroll movement from resonating through shared facility flooring.
Flexible Interconnection: Industrial-grade stainless steel flexible hoses and flanged quick-connect headers simplify parallel piping setups.
Thermal Management: Remote tank positioning stops radiant heat buildup inside the housing, extending internal electronic lifespan.
Performance Mechanics & Efficiency
Scroll Compression:
Orbiting and fixed scroll geometry achieves continuous, pulse-free compression without sliding friction in the chamber.
Direct-Drive Transmission:
Flange-mounted motor connection eliminates belt slip, transmission losses, and periodic tension adjustments.
Staged Control:
PLC-managed sequencing logic brings secondary scroll units online only when system pressure drops below set thresholds.
Low-Temperature Start:
Synthetic thermal-stable bearing grease ensures reliable rotation down to ambient temperatures of 5°C.
System Configuration & Air Treatment
Optimized Sizing: Select base units based on peak volumetric flow rate rather than nominal horsepower to prevent frequent motor cycling.
Filtration Path: Pre-installed 0.01-micron coalescing filters and activated carbon towers remove moisture, aerosols, and hydrocarbons.
Receiver Matching: Pairs with 300-liter or 500-liter vertical epoxy-coated air receivers to dampen pressure ripple effectively.
Dew Point Integration: Optional membrane or desiccant dryers match downstream pressure dew points down to -40°C.
Industry Applications
Pharmaceutical Packaging: Delivers sterile, moisture-free actuation air for blister packaging lines and tablet sorting machinery.
Medical Laboratories: Powers diagnostic equipment, dental chairs, and analytical chromatographs requiring zero hydrocarbon contamination.
Precision Electronics: Supplies clean pneumatic logic for surface-mount pick-and-place nozzles and printed circuit board cleaning stations.
Food Processing: Drives ingredient dosing valves and sorting gates where compressed air directly contacts consumable goods.
Engineering Selection Guide
Peak FAD Calculation: Sum maximum air consumption of all simultaneous tools, adding a 15% safety margin.
Pressure Verification: Determine highest operating pressure at the furthest point, allowing a 0.3 bar maximum piping drop.
Ambient Assessment: Evaluate room ventilation and maximum temperature; select upgraded cooling if ambient exceeds 40°C.
Duty Cycle Planning: Specify continuous 100% duty cycle configurations for multi-shift plants to prevent thermal overload.
Site Installation Requirements
Foundation:
Install on a flat, level concrete floor capable of supporting static equipment weight without specialized pads.
Ventilation Clearance:
Maintain a minimum 800 mm clearance around all access panels for unimpeded cooling airflow.
Piping Diameter:
Utilize a minimum 1-inch main distribution header made of smooth-bore aluminum or stainless steel.
Electrical Compliance:
Connect via dedicated circuit breakers and slow-blow fuses matching full-load nameplate amperage.
Quality Control Standards
Helium Leak Testing: Every scroll housing undergoes high-pressure helium mass spectrometer testing to verify casing integrity.
Performance Benchmarking: Each finished module runs on a computerized test rig for 4 hours to record actual FAD and vibration velocity.
Material Traceability: Aluminum scroll elements and cast-iron crankcases carry permanent heat codes traced to mill test reports.
Electrical Verification: Dielectric withstand testing and ground continuity checks are executed on every control cabinet.
Packaging & Logistics Protocols
Export Crating: Heat-treated solid wood crates complying with ISPM 15 standards protect units against ocean transit shock.
Moisture Seeding: Desiccant bags and VCI films seal internal air passages against saltwater corrosion during container shipping.
Securing Mechanisms: Heavy-duty steel bolting anchors the compressor skid directly to the container floor to prevent shifting.
Documentation: Weatherproof packets containing English operation manuals and calibration certificates are affixed internally.
Frequently Asked Questions
Q: What is the recommended maintenance interval for scroll tips?
A: Scroll tip seals require inspection every 4,000 operating hours and replacement at 8,000 hours, depending on ambient dust levels.
Q: Does this unit require an external oil separator?
A: No. Because the compression chamber operates entirely without oil lubrication, no oil separator is required upstream.
Q: Can multiple units be cascaded to increase total air volume?
A: Yes. Master-slave controller integration allows up to 8 split-type units to operate in parallel, responding dynamically to load changes.
Q: What is the maximum allowable ambient operating temperature?
A: Standard units operate up to 40°C ambient. Special high-ambient configurations rated up to 45°C are available upon request.
