Blowers - Refrigeration and HVAC

Marine refrigeration and HVAC blowers provide forced air circulation through evaporator units, air-handling units, duct systems and machinery-space ventilation systems. They are commonly centrifugal, axial or electronically commutated (EC) types, selected for airflow, pressure, power supply, noise and marine environmental requirements.

ProShipWorks provides end-to-end support to source and supply Blowers for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval

Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.

Applicable Standards & Certification	Selection may involve ISO 5801 or AMCA 210 fan-performance testing, IEC 60092 marine electrical requirements, and applicable EMC and low-voltage directives. Exact conformity depends on the manufacturer and configuration.
Class Approval	Marine class approval is configuration- and application-specific. DNV, ABS, Lloyd's Register, Bureau Veritas and ClassNK may approve complete HVAC or ventilation installations, but not every standard blower model individually.

Installation, Maintenance & Safety Information

Installation Notes	Verify airflow, static pressure, voltage, frequency, rotation, mounting orientation and duct connection dimensions before installation. Use flexible connectors where specified, provide adequate service clearance, and ensure the installation meets the vessel's approved HVAC drawings.
Maintenance Tips	Inspect impeller, housing, filters, bearings, electrical terminals and vibration regularly. Remove salt, dust and condensate deposits, check belt tension where applicable, and record motor current and vibration trends.
Safety Notes	Isolate and lock out electrical power before servicing. Prevent access to rotating parts, use approved lifting methods, and confirm guards are fitted. Do not operate outside the rated voltage, temperature, airflow or pressure limits.
