Datasheet

Product overview

Power: Select exact SWT configuration and package power · Pressure: Obtain selected model working-pressure sheet · Flow: Obtain duty-specific delivered-air performance

SEIZE's dry oil-free screw line is a distinct compressed-air technology from its oil-injected PM packages. The official Chinese two-stage page describes a double labyrinth sealing arrangement with an atmospheric opening between the seals, variable-frequency control and air- or water-cooled versions. It lists 380 V/50 Hz as a supply configuration. The official family illustration is marked SWT-220WV-II.

Select the exact model from required working pressure, delivered-air demand, inlet and ambient conditions and available utilities. Obtain the offered configuration's flow reference conditions, complete-package input power, control range and performance test basis. A model name or a family range is not a substitute for a matched operating point, and data from different stage counts or cooling versions should not be combined into one specification.

Define air quality at the point of use. Dry oil-free compression alone does not establish the moisture, particle and total oil requirements of a complete installed process-air system. Agree treatment, sample location and acceptance method. Where a certificate is required, obtain its actual model coverage, operating conditions, validity and test scope for the offered machine rather than accepting a blanket family claim.

Plan interstage and final cooling, ventilation or cooling-water connections, condensate management, inlet filtration and service access. Agree gearbox and bearing-system maintenance and the required operating and shutdown procedures. For a station purchase, document sequencing, treatment and standby arrangements alongside the compressor. Request the approved general arrangement, electrical and controls documents, performance sheet, model-specific quality evidence and routine spares. Keep installation, commissioning and acceptance responsibilities tied to the same selected SWT configuration and process duty.
