HVLS Ceiling Fans

High Volume Low Speed fans are the most energy-efficient way to circulate large volumes of air in expansive spaces. Operating at low rotational speed with large-diameter blades, they create a gentle, consistent column of air movement that covers areas conventional fans simply cannot reach.

Crystal HVLS fans are available from 8ft to 24ft diameter, with Direct Drive or Gear Reducer AC motor configurations to suit every installation requirement.

  • Fan diameters from 8ft to 24ft (2.44m to 7.32m)
  • Coverage area up to 2,060 m² per unit
  • Direct Drive Permanent Magnet AC Motor or Gear Reducer AC Motor
  • Aerodynamic aluminium blades for maximum airflow efficiency
  • Double pivot adjustable ceiling mount, up to 45° angle adjustment
  • Secure safety cable and safety joints on every installation
  • Power consumption as low as 1.5kW for a full 24ft unit

Centrifugal Fans

Centrifugal fans accelerate airflow radially through an enclosed casing, producing higher static pressure than axial fans of comparable diameter. They are the workhorses of ducted ventilation, process exhaust, dust handling, and high-pressure industrial applications where conventional axial fans cannot deliver the required pressure rise.

Crystal supplies industrial centrifugal fans and blowers through a curated network of manufacturing partners, allowing us to match the specific airflow, pressure, and material requirements of your application.

  • Industrial extractor fans and centrifugal blowers
  • High-pressure designs for process and ducted applications
  • Backward-curved, forward-curved, and radial blade configurations available
  • Single inlet, double inlet, and plug fan variants on request
  • Direct drive or belt drive configurations
  • Multiple casing materials: mild steel, stainless steel, FRP per environment
Specified to your applicationCentrifugal projects are scoped from your airflow, pressure, casing, and environmental requirements. Share your spec and we will return a tailored proposal with model, materials, and lead time.

Pivot Social Fans

Pivot social fans deliver targeted, oscillating airflow exactly where ceiling installation is impractical or undesirable. Wall and column-mounted, with 160° of horizontal oscillation, they cover wide social zones with focused air movement.

Ideal for retail concourses, hotel banquet spaces, restaurants, and any large gathering area where occupant comfort is paramount.

  • Wall, column, or post-mount installation
  • 160° horizontal oscillation for wide coverage
  • Adjustable vertical tilt for targeted airflow
  • Multiple finish options to match interior design
  • Energy-efficient motor operation
  • Low-noise design suitable for hospitality environments

Profile Axial Impellers

Profile axial impellers are precision-engineered rotors at the heart of every axial fan — purpose-built with airfoil or sickle blade profiles bonded to a lightweight aluminium alloy hub. Crystal supplies the complete HasconWing® range from HW Ventilation Italy as standalone components for OEM, retrofit, and aftermarket buyers.

Each impeller is selected against the airflow, static pressure, rotation speed, noise target, and operating temperature of the parent system. Blade material, pitch type, and blade count are configured to suit applications from compressor cooling and engine radiators to ATEX environments and large industrial ventilators.

  • Diameter range: 230 mm to 1,520 mm
  • Operating temperature: -50°C to +300°C (series-dependent)
  • Fixed-pitch & variable-pitch configurations available
  • Airfoil profile (TS, TM, A, De-ALU) for high-efficiency, high-RPM duty
  • Sickle profile (F, C, C-ALU, SR, Q) for low-noise environments
  • Blade configurations from 3 to 20 blades, clockwise or anti-clockwise
  • Plastic, aluminium, and corrosion-resistant blade materials
  • Applications: compressors, radiators, snow cannons, livestock, dryers, ATEX, refrigeration, railway
  • Qualyfan® software-verified airflow on every selection

Flanged Casings

The cylindrical housing that holds the impeller assembly is one of the most under-specified parts of an axial fan — yet it directly determines structural integrity, flange seal, and ease of installation. Crystal manufactures flanged casings in-house using a tube flanging process from a single sheet of metal, producing a one-piece form that is mechanically stronger than welded equivalents.

Casings are sized to your impeller diameter, motor stator, and mounting interface. Standard diameters and bespoke dimensions are both fabricated to order, with bolt patterns matched to the parent installation.

  • Tube-flanged from a single metal sheet for inherent strength
  • No welded seams at the flange — eliminates a common failure point
  • Mild steel, galvanised, and stainless steel options
  • Custom diameters and depths fabricated to order
  • Custom bolt patterns to match existing duct or wall flanges
  • Powder-coat or industrial paint finish available on request
  • Suitable for retrofits, OEM assemblies, and replacement orders

Finger Guards

Finger guards are the wire-form safety mesh fitted to the inlet or outlet of every axial fan. They prevent accidental contact with the rotating impeller while preserving free airflow through the casing. Crystal fabricates finger guards in-house to match every standard axial diameter and to bespoke sizes on request.

Two configurations are available depending on the safety standard your installation has to meet: a single-wire guard for general industrial use, and a double-wire guard for higher-protection environments such as public-facing installations and occupied workspaces.

  • Single-wire configuration for standard industrial duty
  • Double-wire configuration for higher safety requirement zones
  • Available for every standard axial fan diameter
  • Custom diameters fabricated to order
  • Mild steel, galvanised, and stainless steel wire options
  • Powder-coat finish to match casing colour
  • Compliant mounting pattern for fast retrofit on existing casings

Roof Extractors & Motorized Ventilators

Roof-mounted extractors and motorized ventilators evacuate stale, hot, or contaminated air directly through the building envelope. Used in combination with low-level fresh-air intake, they create efficient natural and powered airflow patterns through industrial buildings.

Crystal supplies power-driven and gravity-assisted roof extractor units, available in both metal and impact-resistant plastic constructions, with motorized and free-running configurations.

  • Motorized roof extractor axial fans for forced exhaust
  • Power-driven roof extractors for high-volume air evacuation
  • Metal and high-impact plastic construction options
  • Weatherproof IP-rated enclosures
  • Belt-drive and direct-drive variants available
  • Suitable for warehouses, factories, dairies, kitchens, and chemical processing

  • Custom-configured to your facility's airflow and load requirements
  • Modular construction: filter, cooling coil, heating coil, fan, humidifier sections
  • EC fan options for energy efficiency and variable-speed operation
  • Heat recovery wheels and plate exchangers available
  • Integration with BMS and facility control systems
  • Supplied as part of end-to-end HVAC design and installation

Energy Savings Calculator

How much could you
save with HVLS?

Replace banks of conventional industrial fans with a single HVLS unit and see the impact on your annual energy bill, your CO2 footprint, and your equipment count.

How the math works — in plain terms.
Imagine a 10,000 sq ft workshop. To move enough air through it, you would typically need around 12 conventional pedestal fans (each one covers ~860 sq ft and pulls 0.18 kW). That is roughly 2.16 kW running continuously. One Crystal 16 ft HVLS fan covers the same space at just 1.0 kW — less than half the power, for better airflow.

Run that comparison for the hours and days you operate, multiply by your electricity rate, and you have your annual savings. We translate kWh into CO2 using India's grid average (0.72 kg CO2/kWh, Central Electricity Authority) and into trees using the EPA standard of 22 kg CO2 absorbed per mature tree per year. Numbers are directional — final savings depend on ceiling height, layout, and actual operating pattern.
