VENTILATION

Product catalog summary
Overview: Alfa Electric's filter fans are designed for high performance and easy installation, suitable for various enclosure applications. They offer a modern design with a range of air flow ratings.
Specifications: Made from self-extinguishing ABS material, the fans are available in standard RAL 7035 color, with options for RAL 7032 and custom colors for large orders. They feature a snap-in fixing system for panels with thicknesses between 1.2 - 2.4 mm, with screw kits available for other thicknesses.
Performance: Air flow ratings range from 24 to 630 m³/h, with reversible flow direction on specified models. The fans use high-quality ball bearings, offering a service life of 30,000 hours at 55°C, and provide IP54 protection. They are available in various AC and DC voltages.
Cooling Performance: A diagram illustrates the relationship between cooling capacity, temperature difference, and air flow rate.
Installation and Usage: Fast installation is facilitated by a simple square cut-out and snap-in system. A margin of at least 10% is recommended to compensate for air flow decay due to filter mat clogging.
Product Variants: Various models are listed with different air flow rates, power consumption, and dimensions. Accessories include filter mats, thermostats, and fan speed controllers.
Recommendations: Units with air flow from outside to inside are advised to prevent dust ingress. High filtering capacity mats may reduce air flow rates. DC powered units are recommended to prevent EMC interference.
Additional Features: Roof fans with air flow rates from 600 to 1000 m³/h are also covered, with specifications for different models and power supply requirements.

VENTILATION-1

VENTILATION Filter Fans High performance and fast mounting Modern design A positive visual impact is given by the up-to-date design of the grills and the minimal external projection. All moulded parts are made of highly resistant and self-extinguishing ABS, UL94 VO grade. The standard coIor is RAL 7035. RAL 7032 is also available. On request and for substantial quantities, non standard colors are also available. Fast installation Installation is fast thanks to the simple square cut-out on the enclosure panel and to the snap-in fixing system. No screws are needed. The snap-in fixing system can be used on panels with thickness in the range 1.2 - 2.4 mm. For different thickness, fixing can still be done with the screw kit included in each pack for this purpose. Wide range of air flow ratings The range of air flow ratings goes from 24 to 630 m3/h. For all filter fans, default air flow direction is from the outside towards the inside of the enclosure. If needed the user can easily reverse the direction by simply re-assembling the fan in the opposite way (only on specified models). No interference outside the enclosure 5 mm is the maximum projection outside the enclosure. This means no problems during transportation and enclosure operational life, typical instead of the bigger and cumbersome traditional units. High reliability Alfa Electric only uses the best quality ball bearing fans. They ensure a high efficiency and have an expected life of 30.000 working hours at an ambient temperature of 55°C. They are all designed to ensure a quick and safe electrical connection. Optimal enclosure protection The special configuration of the grill, the self-adhesive gasket and the filter mat ensure an IP54 protection degree towards the enclosure. Power supply Alfa Electric filter fans are available in the following AC supply voltages: 230V single-phase, 115V single-phase and 400V three-phase, all bi-frequency 50-60 Hz. In addition, 24 and 48VDC versions are available up to 230 m3/h. On request they can also be available with other rated voltages not shown in this catalogue. Filter units To achieve optimal cooling air circulation, filter fans are used together with filter units. Filter units are available in four different sizes and have the same design of the external part of a filter fan. ael-cat-en-15.01 - Specifications, values and drawings are subject to change without notice.
