CANARM

CANARM upblast exhausters are designed to discharge exhaust air vertically away from the building surface, which helps prevent grease and odors from accumulating on walls or being drawn back into intake vents. Standard wall-mount exhaust fans typically discharge horizontally. Upblast models are common in commercial kitchen exhaust systems where the airstream contains grease. Both types may be belt-drive or direct-drive, and both can be supplied with or without drive packages. Selection depends on the installation orientation, local code requirements, and the desired discharge direction.

CANARM kitchen air belt-drive fans are available with motors rated for 115/230V AC single-phase, 230/460V AC three-phase, and 575V AC three-phase. The specific voltage depends on the model and horsepower. For example, the ALX135UBT10033 uses a 1/3 hp motor at 115/230V, while the ALX210UBT30150P uses a 1 1/2 hp motor at 575V. When ordering, verify the available power supply at the installation site and select the corresponding motor voltage and phase. 3G Electric lists voltage and phase in the specifications for each SKU.

Many CANARM belt-drive fan models are supplied assembled and include a drive package consisting of sheaves, belts, and any required bushings. This reduces installation time and ensures that the drive components are matched to the fan and motor. However, not all models include a drive package by default, so it is important to check the product description or specification sheet. The SKUs listed by 3G Electric indicate whether a drive package is included. If a drive package is not included, it must be ordered separately or sourced to match the fan's speed and horsepower requirements.

CANARM upblast exhausters in the kitchen air belt-drive line cover airflow capacities from approximately 1,400 cfm to over 5,600 cfm. Specific examples include the ALX135UBT10033 at 1,405 cfm with a 13 1/2 inch wheel, and the ALX245UBT30150P at 5,668 cfm with a 24 1/2 inch wheel. The required airflow depends on the size of the kitchen hood, the cooking equipment, and local exhaust requirements. Static pressure also affects fan selection, so both airflow and static pressure must be considered. 3G Electric provides performance data for each model to assist in matching the fan to the application.

ODP stands for Open Dripproof, which is a motor enclosure type. An ODP motor has ventilation openings that allow air to circulate for cooling, but the openings are designed to prevent drops of liquid from entering at angles up to 15 degrees from vertical. ODP motors are suitable for indoor applications where the motor is protected from direct water spray or heavy moisture. They are not rated for washdown or outdoor exposure without additional protection. In CANARM fans, ODP motors are common for kitchen exhaust and general ventilation where the motor is mounted outside the airstream or in a protected location.

Selecting a CANARM fan for commercial kitchen exhaust involves determining the required exhaust airflow in cfm, the system static pressure, the available electrical supply (voltage and phase), and the installation orientation (wall-mount, upblast, or roof-mount). The fan must be rated for the airflow and static pressure at the operating point. Additionally, the fan should be constructed for grease-laden airstreams if it handles kitchen exhaust. Belt-drive models allow speed adjustment via sheave changes to fine-tune performance. 3G Electric can provide specification sheets and quotation support to help match a CANARM model to the application requirements.
