Ask28t Specifications, Features & Compatibility Guide

The Kaeser ASK28T is a 15 kW stationary floor-mounted rotary screw compressor designed to meet the demands of continuous industrial duty cycles.40 m³/min at 10 bar.

Quick Answer

The Kaeser ASK28T is a robust choice for Indian businesses requiring a consistent, high-volume compressed air supply. Its 15 kW motor and efficient SIGMA PROFILE pump deliver reliable 3.17 m³/min at 6 bar, perfectly suited for heavy industrial applications or large workshops. Choose the ASK28T for long-term operational savings and unwavering performance in continuous industrial duty cycles, where downtime is costly.

Opt for the Kaeser ASK28T if your industrial facility demands unwavering, continuous compressed air for critical operations, valuing long-term efficiency and reliability. Avoid if your application is small-scale, intermittent, or if initial low capital expenditure is the primary concern over robust, high-performance industrial duty.

Product Overview
The Kaeser ASK28T is a 15 kW stationary floor-mounted rotary screw compressor designed to meet the demands of continuous industrial duty cycles. Operating on a 400V three-phase 50 Hz supply, this unit utilizes a belt-driven SIGMA PROFILE pump to generate 3.17 m³/min of free air delivery at 6 bar and 2.40 m³/min at 10 bar. The system weight of 580 kg is stabilized by anti-vibration mounts and encased in a powder-coated steel frame with extensive noise insulation to achieve a quiet 65 dB(A) output. To ensure air quality, the ASK28T includes an integrated ABT 40 refrigeration dryer and an automatic moisture separator. System monitoring is handled by the SIGMA CONTROL2 digital display, which provides real-time service indicators, pressure switch management, and thermal protection. For piping integration, the unit features a G 1¼ air outlet port, making it compatible with high-flow industrial pneumatic tools.

Engineering Analysis
Engineering of the Kaeser ASK28T centers on the SIGMA PROFILE air end, which optimizes the ratio of 15 kW power consumption to 3.17 m³/min air volume at 6 bar. The belt drive mechanism allows for precise speed control of the electric induction motor, contributing to the IE3 efficiency rating and the moderate 65 dB(A) sound pressure level. Thermal management is critical in this oil-injected setup, utilizing an air-cooled configuration and integrated thermal protection to maintain performance during continuous run cycles. The integration of the refrigeration dryer within the 1460 mm depth footprint eliminates the need for external drying units, reducing pressure drops between the pump and the G 1¼ outlet. Structural stability for the 580 kg mass is provided by the powder-coated steel frame, while the SIGMA CONTROL2 logic handles auto-cutoff and overpressure protection to prevent mechanical stress during fluctuating demand.
