Split-Type Medium Air Displacement Oil-Free Scroll Air Compressor
The split-type architecture decouples the oil-free scroll air end assembly from the air receiver and post-treatment units, allowing the compressor head to be positioned near point-of-use or inside sound-dampened utility rooms while remote storage handles peak demand buffer. Twin-core scroll modules operate asynchronously based on real-time air consumption, preventing idle energy waste.

Architecture & Layout
Decoupled Chassis: Separates the compressor head from the vertical receiver tank, eliminating vibration transmission and simplifying pipeline routing in constrained equipment rooms.
Thermal Isolation: Isolates high-temperature compression chambers from electronic control panels, extending inverter lifespan in ambient temperatures up to 45°C.
Modular Footprint: Enables multi-unit cascading configuration within narrow utility corridors, reducing linear floor space occupancy by 35% compared to monolithic package units.
Vibration Dampening: Multi-stage polyurethane mounts absorb low-frequency oscillation generated during continuous scroll orbit cycles.
Performance Metrics
Tip Seal Durability:
High-strength engineering polymer tip seals maintain volumetric efficiency above 94% across 10,000 continuous operating hours.
Thermal Management:
Dual-flow centrifugal cooling fans paired with finned aluminum heat exchangers restrict discharge air temperature to ambient +12°C.
Dynamic Balance:
Counter-balanced crankshaft design restricts structural vibration velocity to under 1.8 mm/s.
Demand-Load Control:
PLC-based sequencing activates individual scroll modules incrementally according to live system pressure fluctuations.
System Configuration
Dual-Core Integration: Houses independent 3.7 kW or 5.5 kW scroll air ends within a single split cabinet, providing operational redundancy.
Dew Point Control: Achieves a pressure dew point down to -40°C when paired with an integrated regenerative desiccant dryer module.
Pre-Filtration: Standard configuration includes dual-stage particulate and coalescing pre-filters capturing solid particles down to 0.01 micron.
Receiver Matching: Designed for compatibility with 300L to 500L vertical ASME/CE certified galvanized air receivers.
Application
Medical Laboratories: Powers diagnostic tools and hospital ventilation systems requiring sterile, odorless, and moisture-free gas supply.
Electronics SMT Lines: Supplies actuation air for surface-mount pick-and-place machines without risk of oil varnish on microchips.
Pharmaceutical Dosing: Drives blister-packing lines and pneumatic valves where strict pharmacopeia contamination limits apply.
Food & Beverage Processing: Operates sorting gates and liquid filling nozzles in direct contact with consumable items.
Selection Guide
Displacement Sizing: Calculate total peak LPM demand of downstream pneumatic actuators and multiply by a 1.25 safety factor for continuous duty.
Pressure Rating: Choose 0.8 MPa for general automation; specify 1.0 MPa if long distribution headers induce pressure drops exceeding 0.05 MPa.
Grid Matching: Verify local industrial grid supply; specify dual-frequency inverter-driven models for global export machinery integration.
Enclosure Protection: Select IP55 rated enclosure options for high-humidity or dusty manufacturing shop floors.
Installation Requirements
Foundation Loading:
Requires a level, reinforced concrete floor supporting static loads of 350 kg/m² without specialized inertia pads.
Ventilation Clearance:
Maintain a minimum 800 mm clearance around cabinet perimeters and ceiling exhaust vents to ensure unobstructed airflow.
Pipe Connection:
Utilize Schedule 40 stainless steel or corrosion-resistant aluminum distribution piping sized to match DN25/DN32 outlet flanges.
Power Cabling:
Connect via dedicated 4-wire armored copper cables protected by slow-blow thermal magnetic circuit breakers.
Quality Verification
Air Purity Testing: Every compressor undergoes particulate and hydrocarbon vapor analysis via laser particle counters per ISO 8573 standards.
Pressure Proofing: Pressure vessels and internal discharge lines undergo 1.5x pneumatic proof pressure testing for 30 minutes.
Burn-In Testing: 4-hour full-load factory run-in tests record vibration spectra, current draw stability, and thermal equilibrium metrics.
Material Traceability: Raw casting batches for scroll housings undergo spectrometer chemical composition analysis prior to CNC machining.
Packaging & Logistics
Export Crate Spec: Heat-treated fumigation-free plywood crates conforming to ISPM 15 standards, lined with moisture-barrier vacuum foil and desiccants.
Transit Protection: Unit base bolted directly to heavy-duty skids with shock-absorbing suspension brackets preventing impact damage.
Documentation Pack: Factory test reports, ISO 8573 Class 0 certificates, wiring schematics, and multilingual manuals packed in waterproof enclosures.
Volume Metrics: Single crate volume averages 1.8 m³ to 2.4 m³ depending on integrated receiver and dryer accessories.
Frequently Asked Questions
Q: How often must scroll tip seals be inspected and replaced?
A: Scroll tip seals require visual wear inspection every 4,000 hours and scheduled replacement between 8,000 to 10,000 operating hours based on ambient dust levels.
Q: Can the split configuration operate in ambient temperatures above 40°C?
A: Yes, units operate up to 45°C ambient, though continuous operation above 40°C requires derating discharge capacity by 5%.
Q: Does the split system require specialized foundation bolting?
A: No, due to the balanced orbiting mechanism and internal vibration isolation mounts, the unit does not require permanent floor bolting.
Q: What is the maximum separation distance between compressor head and receiver tank?
A: Recommended maximum interconnection piping length is 15 meters to minimize pressure drop and maintain responsive pressure sensing control.
