CAB

Product catalog summary

Application: The CAB in-line duct fan is designed for quiet operation, suitable for use in public buildings, libraries, conference rooms, offices, restaurants, classrooms, and audio studios.

Construction: The fan housing is constructed from galvanized sheet steel with a 50 mm thick fire-resistant acoustic layer. It features an open housing for easy access to the impeller and motor, circular connection joints with rubber gaskets, and four mounting brackets for versatile installation.

Motor: The fans are equipped with asynchronous, single-phase motors with various voltage and frequency specifications depending on the model. They support voltage-controlled speed control and have different protection and insulation classes.

Technical Specifications: Detailed specifications for each model include voltage, speed, power, current, airflow, operating temperature, sound pressure level, weight, and regulator compatibility. For example, the CAB 100 model operates at 230V, 1390 rpm, with a maximum absorbed power of 42W and airflow of 190 m3/h.

Performance Curves and Acoustic Characteristics: Performance curves show static pressure, absorbed power, and airflow for different models. Acoustic characteristics are detailed in tables, showing sound levels at various frequencies for inlet, outlet, and emitted noise.

Dimensions: Dimensions for each model are provided, detailing measurements such as A, B, C, ØD, E, F, and G.

Accessory Assembly: A list of compatible accessories is provided, including channel filters, backdraft shutters, antivibration connectors, flexible silencers, and more, with specific part numbers for each model.

Overview: The document provides technical specifications and characteristics for CAB in-line duct fans, including both residential (RVU) and non-residential (NRVU) ventilation units. It includes details on electrical accessories, ERP characteristics, and mounting accessories.

Specifications:

Mounting Accessories: Dedicated to 160 mm diameter, including filters, shutters, connectors, silencers, throttles, vents, diffusers, and heaters.
Electrical Accessories: Includes thermostats, sensors, humidistats, and various types of regulators for different CAB models.

ERP Characteristics:

Residential Ventilation Units (RVU): Features include variable speed drives, no heat recovery system, and specific energy consumption (SEC) class F. Maximum flow rates and electric power inputs vary by model.
Non-Residential Ventilation Units (NRVU): Similar features to RVUs with additional specifications like static efficiency of fans and face velocity. No heat recovery system is applicable.

Key Parameters:

Sound power levels range from 34 to 61 dB(A) depending on the model.
Maximum external leakage rate is consistently 3% across models.
Annual electricity consumption is specified for average, warm, and cold climates.

Relevance: The document is crucial for understanding the technical capabilities and limitations of CAB in-line duct fans, aiding in selection and installation processes.

Catalog excerpts

CAB in-line duct fan APPLICATION Very quiet operation makes CAB ideal for ventilation of public buildings, libraries, conference rooms, offices, restaurants, classrooms, audio studios, etc. Housing made of galvanized sheet steel, fire resistant acoustic (MO fiberglass) layer 50 mm thick. Impeller with forward curved blades of galvanized sheet steel. Circular connection joints with rubber gaskets. The open housing allows access to the impeller and motor without dismantling the fan from the installation. The housing cover is fitted with locks for fast inspection without additional tools. All models are also equipped with four mounting brackets to allow the fan to be installed on a wall, floor or ceiling. As standard the device is designed to be mounted directly to the outside. The fans are equipped with asynchronous, single-phase 230V, 50/60Hz (models 100, 125, 150, 160), 230V, 50Hz (models 200, 250N, 315 RE, 355 RE, 400 RE), with ball bearings. CAB 100 - CAB 250N models have IP44 protection rating, insulation class B, CAB 315 RE - IP44 protection class, insulation class F, CAB models 355 RE - CAB 400 RE - IP55 protection class, insulation class F. All motors are designed for voltage-controlled speed control. Electrical connection diagram - fig. 9, p. 663.
