30kW Direct Drive Rotary Screw Air Compressor | 40HP · 1.5 m³/min @ 10 bar | CE Compliant for German Market

Overview

The 30kW (40HP) single-stage direct drive rotary screw air compressor delivers 1.5 m³/min free air delivery at 10 bar in a compact footprint of 1100 × 850 × 1350 mm. Designed as a fixed-speed industrial workhorse, it pairs a 1:1 direct-coupled drive with a single-stage airend—eliminating belt wear, reducing maintenance intervals, and sustaining reliable compressed air supply for continuous manufacturing operations.

For German industrial buyers evaluating compressed air systems under tightening EU efficiency rules, this unit targets the sweet spot: sufficient capacity for workshop-scale pneumatic demand, minimal installation footprint, and a drive architecture that removes one of the most common causes of unplanned downtime.

Technical Specifications

Why Direct Drive Matters for German Operations

Belt-driven compressors introduce a predictable failure point. Belts stretch, slip, and require periodic retensioning and replacement. In a 24/7 production environment, that translates into planned downtime, consumable costs, and energy losses through belt slip. The direct drive architecture used in this unit connects the motor shaft to the airend via a precision flexible coupling—no belts, no tensioners, no slip losses.

The practical consequences for German buyers:

• Lower lifecycle energy consumption. Direct drive eliminates the 3–5% transmission loss typical of belt systems, which compounds significantly over a 10-year service life.

• Reduced moving parts, fewer wear points. No belt or pulley set means less heat generation, lower vibration, and a maintenance schedule focused on oil and filters rather than mechanical transmission components.

• Fewer unplanned stoppages. For operations running two or three shifts, the absence of a belt as a sacrificial component directly improves compressed air availability.

  Compliance and Documentation for the German Market

  Germany enforces compressed air system requirements through a layered regulatory framework. This unit is supplied with documentation structured for integration into German production environments:

  CE Marking and Declarations. Complete machinery bearing the CE mark is accompanied by an EU Declaration of Conformity under Machinery Directive 2006/42/EC, covering the applicable safety, EMC (2014/30/EU), and RoHS requirements. If the compressor is supplied as a partly completed machine for integration into a larger compressed air station, the documentation package includes a Declaration of Incorporation and installation instructions, with the integrator responsible for final CE conformity assessment.

  Pressure Equipment. For a 10 bar working pressure and the receiver volume of this class of compressor, the pressure vessel falls under PED 2014/68/EU. The documentation includes the required conformity assessment pathway, pressure test records, and material certificates for pressure-bearing components.

  Energy Efficiency Declaration. Under the EU Ecodesign framework, compressed air systems with drive motors and cooling fans fall within scope for efficiency disclosure. From July 2026, Regulation (EU) 2024/1834 supersedes Regulation (EU) No. 327/2011, shifting assessment from the motor in isolation to the entire system—motor, control system, aerodynamics, and attached components. Relevant energy efficiency data (motor efficiency class, test report reference, and carbon footprint parameters) is available for EPREL synchronization and structured data disclosure as required for B2B industrial equipment listings.

  Noise. German workplace regulations require hearing protection to be made available at 80 dB(A) and mandate that work without hearing protection stop at 85 dB(A). A compressor operating at or below 72 dB(A) sits comfortably below both thresholds, simplifying workplace risk assessment under the Lärm- und Vibrations-Arbeitsschutzverordnung and reducing the need for organizational noise-control measures.

  Total Cost of Ownership: Where This Unit Fits

  German industrial buyers increasingly evaluate compressors on lifecycle cost rather than purchase price alone. Energy typically accounts for approximately 80% of a compressor's total cost of ownership, with the purchase price representing only about 20% and maintenance the remainder. German buyers prioritize energy efficiency, operational reliability, and environmental performance when identifying suitable solutions, then compare lifecycle costs, maintenance requirements, and system performance before selecting suppliers.

  This 30kW unit addresses TCO in three concrete ways:

  1. Fixed-speed efficiency at a stable load point. If the compressed air demand profile is relatively constant—common in workshop-scale manufacturing, packaging lines, and pneumatic tool stations—a fixed-speed direct drive compressor runs near its design efficiency point, avoiding the part-load penalties of oversized variable-speed units.

  2. IE4-class motor alignment. Leading German compressor manufacturers now equip 30kW and larger screw compressors with IE4 Super Premium Efficiency motors as standard, recognizing the lifecycle energy savings that justify the motor upgrade. This unit is specified for equivalent high-efficiency motor performance, positioning it competitively against established German brands on energy consumption per cubic meter delivered.

  3. Maintenance simplicity. No belts, no tensioner assemblies, no alignment procedures. Routine maintenance focuses on airend oil, oil filter, air filter, and separator—with service intervals documented in the supplied maintenance manual.

     Application Fit

     This compressor is sized for small-to-medium industrial compressed air demand:

     • Metalworking and machining workshops — pneumatic clamping, blow-off, tool actuation

     • Automotive service and repair facilities — impact tools, lifts, paint preparation

     • Packaging and labeling lines — actuator and cylinder supply

     • Woodworking and furniture production — stapling, spraying, clamping

     • General manufacturing — where 1.5 m³/min at 10 bar covers the aggregate demand of multiple workstations

     The 1100 × 850 × 1350 mm footprint and 350 kg weight allow installation in a dedicated compressor room or a protected corner of the production floor without requiring structural reinforcement. Air-cooled design eliminates the need for cooling water connections.

     What German Buyers Should Confirm Before Ordering

     German B2B procurement for industrial equipment emphasizes documentation completeness and parameter verification over marketing language. The following items are standard components of the quotation and technical documentation package:

     • EU Declaration of Conformity (or Declaration of Incorporation, depending on supply scope) with referenced directives and harmonized standards

     • Pressure vessel documentation per PED 2014/68/EU, including material certificates and pressure test report

     • Noise test data under ISO 2151 or equivalent, stated at the specified measuring distance

     • Motor efficiency class and test report reference

     • Energy efficiency data sheet structured for EPREL compatibility

     • Installation and commissioning manual in German

     • Maintenance schedule with recommended service intervals and consumable part numbers

     • Warranty terms — standard 12 months from commissioning or 18 months from shipment, with extended coverage available
