Generic image, in some models the real foot may differ from the shown image
• Specially designed for speed frequency control in ventilation applications.
• Ultra compact, simple operation and wide range of functions.
*Dial panel incorporated. Optional EMC filter.
Protection index IP20.
The selection of SFC frequency drive speed controller must be made based on the maximum intensity absorbed by the fan to be regulated. The powers (kW) and the intensity for constant load refer to the normal duty (150% overload for 60 seconds). The intensity for quadratic load admits an overload of 110% during 60s.
SFC 230: Entrance 230V I, exit 230V III
SFC 400: Entrance 400V III, exit 400V III
EMC filter incorporated for models from 47A (included)
*Lineal load rated current
**Quadratic load rated current
• Support of great radial and axial elasticity.
• These low-profile, compact and elastic supports control the three directions of movement with large deformations in the rubber.
• It consists of two parallel armour adhered to the bell-shaped rubber and by a base with handles.
• These supports with handles have a threaded hole in their upper frame and are easy to install and fix.
• The steel protection washer allows it to withstand overloads by increasing its rigidity and protects the rubber from dripping hydrocarbons.
• Elastomer type NR or high quality elastomer. Working temperatures between -40ºC and + 70º C.
• Taking into account the tolerances of hardness in the elastomers, the mechanical characteristics of these series may differ.
• Range of 6 sizes and 3 different hardnesses (45-60-75) to fit a load range between 2 Kg and 1300 Kg.
1. Soft: hardness A 45
2. Average: hardness B 60
3. Hard: hardness C 75
• Very appropriate in the elastic suspensions of machines that present vibrations of horizontal components.
• Metal insulators designed to work with compression with 85% insulation according to the following arrows (travel in mm) and rpm:
Arrow (mm.) r.p.m.
20 mm >600 r.p.m.
30 mm >500 r.p.m.
• Made of high quality elastic steel, with rectangular base and rubber mat to improve the grip. It treats of a resistant product and easy assembly, that avoids all type of vibrations of the fans to the structure of the premises.
• Operating temperature from -45 ° C to + 120 ° C.
• To install under machines with rotating components, ventilation groups, fans, ventilation boxes, etc.
Structure made of extruded aluminum profiles available in different dimensions according to the panel to be installed and the fan volume. The profiles joining is made of polyamide corners, which gives them great strength and the possibility of disassembling the structure into pieces.
Panels can be made of a single sheet with inner insulation of 10 mm thick polyethylene foam, or 2 sheets (sandwich panel) with thicknesses of 25 mm or 50 mm, depending on the required attenuation degree.
The sheets of each panel can be galvanized steel, galvanized steel with coloured plastic coating or stainless steel.
The lower part is finished off with a structure / plinth for transport and handling, made of galvanized sheet or upn-80/100 joist, depending on the cabin dimensions and weight.
The air inlets and outlets of the cabin have anti-vibration tarpaulins coupled to mounted fans. These fans rest on a floating base with acoustic dampers.
