Usha Exhaust Fan Plastic 12″

Description

The Usha Crisp Air LX (300mm / 12-inch) is a sleek, high-performance ventilation fan designed to effectively eliminate odors, moisture, smoke, and stale air from indoor environments. Constructed completely out of premium, high-grade rust-proof plastic, this fan is specifically tailored to withstand high-humidity environments like kitchens and bathrooms without corroding. It features an aerodynamically designed 5-blade system that maximizes air delivery while maintaining ultra-quiet operation. The back of the fan is equipped with automatic shutters that open seamlessly via airflow when the fan is switched on and snap tightly shut when turned off, keeping out dust, outdoor debris, lizards, and insects. Key Specifications: Sweep Size: 300 mm (12 inches) Material: 100% Rust-proof polymer body and blades Color: Clean White Shutter Mechanism: Automatic back-draft shutters Ideal for: Large kitchens, bathrooms, pantries, and small office cabins Compatible Installation Mechanisms To function properly, this unit relies on several physical compatibility factors and structural installations: 1. Wall/Window Cutout Dimensions (Mounting Compatibility) Duct / Frame Size: Being a 12-inch (300mm) sweep fan, it requires a square wall opening or glass window cutout of approximately 350mm x 350mm (roughly 14 x 14 inches) to accommodate the rear frame casing and shutter mechanism. Surface Profiles: It can be securely flush-mounted into wooden panels, concrete walls, or integrated directly into window glass panes using a standard standard glass-cutting ring installation. 2. Electrical Mechanisms Power Supply: Operates on a standard domestic single-phase AC mechanism (220V – 240V @ 50Hz). Power Consumption: Energy-efficient motor mechanism drawing roughly 45W to 55W of power. Control: Compatible with standard single-pole wall toggle switches or pull-cord switches. It is generally not recommended to use a standard ceiling fan resistive dimmer regulator with this motor unless it is explicitly rated for exhaust fan inductive loads. Installation Tip: Ensure the unit is installed at a height of at least 7 feet from the floor level for optimal cross-ventilation and to keep the automatic shutters safe from accidental physical obstructions.
