DESCRIPTION TN/HN direct driven fans are designed for light industrial applications. They are used to convey clean or lightly polluted air and non-aggressive gases. The fan casings are not gas tight. The permissible temperature range of the conveyed medium is -30oC to +60oC. The housing of the fans is made of galvanized sheet steel. Painted or powder coated casings are available. The TN type unit has forward-curved impellers which are made of galvanized steel, designed for high circumferential speed. The inlet cones are manufactured from galvanised steel or glass fibre reinforced polyamide. The HN type unit has backward-curved impellers are made of seawater proof aluminium. Their low mass moment of inertia allows reducing motor sizes. The inlet cones are made of galvanised steel. All fan impellers are statically and dynamically balanced in two plains to quality level G 2.5 (DIN ISO 1940). All fans are also equipped with standard IEC-motors of flange or foot type. Protection class is IP55 and isolation class F. The permissible ambient temperature range is -20oC to 40oC. Up to motor size 100, voltage controllable motors are available. All units can be executed as fitted type fans with a B5 flange motor (TNF/HNF). The side plates and the scroll plate are joined together by a standing seam. The mounting feet are screwed to the fan casing. The discharge orientation can therefore easily changed in step of 90o. The TNQ/HNQ type fans feature a square side plate that allows the installation of a B3 foot motor. The side plates and scroll are riveted. All presented data accords to 50Hz supply. DIMENSIONS

DESCRIPTION Marine centrifugal fans WPM are destined for operation in the ventilation systems of seagoing ships with unrestricted cruising area as well as offshore objects. They may be used as exhaust or supply fans and be installed inside the compartments. WPM fans are of compact, sturdy construction and equipped with high efficient impeller with backward-curved blades. Working parameters of fans are shown on performance curves Pt=f(V) with respect to inert gas of specific density �=1,2kg/m3 and temperature t= 20oC, where: Pt (Pa) – fan total pressure, V (m3/s) – air displacement. Allowable tolerances of working parameters of fans (air displacement, pressure, power consumption and efficiency) are in accordance with standard PN-77/M-43021. Temperature of conveyed medium should not exceed +45oC, dust contents 0,3g/m3.�Surface treatment – hot-dip galvanized. Housing is made of carbon steel. Impeller is made of sea water resistant aluminum alloys. Electric motor is executed as marine, induction, squirrel-cage and three-phase. It is suitable for 50 or 60Hz electric installation. Smaller motors are coupled directly to fan casings, larger fitted on supporting pedestal. Fans in explosion-proof execution are fitted with brass lining on inner surface of housing in way of impeller. On request fans may be supplied with flanged flexible connections for inlet and/or outlet and set of shock absorbers. MARKING Example: WPM type fan of nominal diameter DN=160, with impeller speed 3500 min-1, with RD0 position: WPM 160/4-RD0 TECHNICAL SPECIFICATION & DIMENSIONS Impeller speed: 1 – 1450 min-1 (50 Hz) 2 – 2900 min-1 (50 Hz) 3 – 1750 min-1 (60 Hz) 4 – 3500 min-1 (60 Hz) Discharge orientation viewed from drive side

DESCRIPTION Marine aluminum portable centrifugal fans WPMA/P-140 are destined for supply or extract of air from spaces of seagoing ships or offshore object, that are not provided with forced ventilation system. Operating data of fans are presented on enclosed performance curves Pt=f(V), where:

Pt – total pressure, Pa, V – airflow, m3/s.

Allowable tolerances of operating conditions (airflow, pressure, power consumption and efficiency) comply with the standard PN-77/M-43021. Temperature of conveyed medium must not exceed +45oC, dust contents 0,15g/m3. Housing and impeller of WPMA/P fans are made of sea water resistant aluminum alloy, welded. Electric motor is induction type, squirrel cage, three-phase, in marine execution. Electric supply: 50 or 60Hz. Fans are provided with WPD-381 start/stop switch and 20m long supply cable without terminal connector. Accessories: storage aluminum box (standard outfitting), DN160 flexible hoses (number of hoses must be specified at the order). MARKING Example: WPMA/P-140 destined for operation in 50Hz electrical installation: WPMA/P-140-50 Hz TECHNICAL SPECIFICATION & DIMENSIONS
