Fantech Gamma Downflow Series CE314D

Description

High-Performance Downflow Ventilation for Demanding Trade Applications

The Fantech Gamma Downflow Series CE314D is engineered for efficient, high-capacity exhaust performance in commercial ducted systems where airflow reliability matters. Designed with backward-curved centrifugal impellers and multiple material options (plastic, steel, or aluminium), this unit delivers strong, stable extraction across a wide range of site conditions.

With compact, low-profile construction, the CE314D is ideal for installations where space is limited but performance cannot be compromised. Available in multiple sizes ranging from 192mm to 710mm across the Gamma Series, it supports flexible project requirements from small commercial setups through to large-scale ventilation systems.

Twin vertical discharge fan configurations provide up to 100% standby capacity, ensuring uninterrupted operation in critical environments. Combined with multi-speed options and 3-phase 2-speed star/delta configurations, this unit gives electricians and contractors the control needed to match system performance precisely to job demand.

Built for Compliance, Durability, and Long-Term Reliability

Designed with trade-grade durability in mind, the CE314D features UV-stabilised plastic cowls and corrosion-resistant steel components, ensuring long service life even in exposed or harsh environments. Standard bird mesh protection prevents pests and debris from entering ductwork, helping maintain system cleanliness and airflow efficiency.

All motors include thermal protection as standard, along with sealed-for-life ball bearings to reduce maintenance requirements and extend operational lifespan. The external rotor squirrel cage induction motor is available in both 230V single-phase and 415V three-phase (50Hz) configurations to suit a wide range of electrical setups.

Airflow performance is tested to ISO5801:2007 standards, while noise performance is verified to BS848: Part 2 (1985), giving contractors confidence that installations meet expected performance and acoustic requirements. With mounting flexibility of up to 30°, installation is easier across varied roof and plant configurations.

Trade-Friendly Installation, Control, and Project Efficiency

The Fantech Gamma CE314D is built to streamline installation and reduce on-site complexity for licensed electricians and HVAC contractors. Its compact design and lightweight construction make handling and positioning easier on-site, helping save time during installation and commissioning.

Speed control options via electronic or auto-transformer controllers (excluding CE316) allow fine-tuning of airflow to match system requirements, improving overall efficiency and system balance. Twin fan models include standard shutters, with optional shutters available on single fan units, allowing tailored system design based on project needs.

Engineered for downflow exhaust applications, this unit is well suited for commercial buildings, plant rooms, and facilities where reliable extraction and straightforward integration into ducted systems is essential. Whether working on new builds, upgrades, or maintenance replacements, the CE314D helps contractors deliver consistent results with fewer site delays.
