HVLS Fan (High Volume Low-Speed Fan)

What is an HVLS Fan?
Simply put, an HVLS fan is one that delivers High air Volume at Low Speed. Generally, HVLS fans are larger than 7 feet (2.1 m) in diameter and are designed for industrial spaces and businesses. These large ceiling fans help circulate the air better and cool the interior space to make the work environment more tolerable, especially if multiple machines are working and throwing off heat.

The high volume portion means that the fan moves higher amounts of air than the cumulative flow of smaller models. The low speed is just what it says, meaning the fan moves at a slower speed, but in turn, using up to six times less energy than traditional ceiling fans. Our HVLS fans are crafted from premium materials by expert craftsmen, lending quality performance to your business or large space.

CREATIVE IDEAS

AT Maya Fans we always remain creative to deal with the challenges in the field of tailor-made HVLS fans. So-far we have developed fan for up to 200 mm chord width for low RPM and low sound fan.



EXCELLENT FEATURES

We are a pioneer to introduce the most efficient FRP profile. we also introduce many more features in design as well as in manufacturing.



FULLY RESPONSIVE

AT Maya Fan We never force-fit our standard existing fans. But remain responsive to input design data and develop new products as and when it required.

HVLS FAN DEVELOPMENT PROCESS

Every User have a different requirment of HVLS. So they require a customized fan. And we do not Force customer to compromise with the standard available product. But remain open for new development. and the following are the step for customized HVLS fan developments-

FAN DATA COLLECTION

It is must to have accurate data (Fan duty point) for fan development. So we do collect data on the field with our technical expertise and high-tech equipment.

FAN DESIGN

We analyze collected data and conclude for a specific design point. As well as keep a range of operations in mind while developing a new fan.

VALIDATION

It is must to confirm each of the design outcomes. It helps to decide on the best solution, and we have full modelling and testing facilities in the house.

PRODUCTION

Once the final fan design concluded, it handed over to the production team. They prepare the tool for production.

Why choose Maya HVLS fan?



Low Operating Costs

Maya High efficient airfoil blade design
Optimization of twist cord and cross-section provide high efficiency.
The involvement of the most advanced composite material. Reduces turbulence and produces smooth linear airflow.
Best design for the duty point No oversizing of the fan.



Long Life Construction

Most of the part made of Heavy-duty composite and hot-dip galvanized material. It meets the corrosion resistance and equipment life requirements of heavy industrial applications. While still delivering an outstanding value.
Lightweight impeller, thus, increases in the life of all the mechanical components.
HVLS Fans are also available with Series 300 stainless steel. It is an optional upgrade which comes with a 5-year limited warranty.
Maya HVLS Fans manufactured in ISO-2015 certified facilities. It attests to our commitment to comprehensive quality processes and systems.



Fast emergency response.

Ready-made fan available.
The minimum stock of the fan spare maintained.
Low manufacturing time because of zero outsourcing.
An expert team available for fan installation.



Quiet by Design

The composite blade has a glossy surface finish that offers smooth airflow.
low tip speed design (Nose are directly proportioned to tip speed).
No outsourcing full quality control thus achieves least tip clearance.
Special design available for extra low noise fan which can reduce noise up to 10 dba compares to conventional fans.



Performance for All Seasons

The fan is a constant flow machine. To maintain its performance, despite critical variation in weather our fans designed for a broad range of operations. Our fans are having a good amount of reserve margin for both airflow and static pressure. Thus fan performs throughout the year in all type of seasons.



Low Maintenance/Less Downtime

Maya FRP HVLS fans made of high-quality material and robust design.
Maya design fan for low operating tip speed, it increases system life and also reduces the chance of failure.
Unlike the painted fan, we do provide a permanent coating of a gel coat that remains an integral part of the fan blade body. And it does not get separated due to erosion.

Here is the list of Maya HVLS fan component with a there brief detailing

Z

Fan Blade

Maya HVLS fan blade made of latest airfoil similar to an aeroplane wing. We do select the most advanced airfoil possible for the fan to provide maximum efficiency. Due to this, we achieved superior performance. Our blade is robust in construction and designed for 7-10 times of operating load. We also provide superior wear resistance material to maintain surface stability for a long period of time. This prevents efficiency deterioration over a period of time.

This FRP HVLS fan blade is having some of the very charismatic property. It is very much possible to produce any complicated shape with ease. Thus provide an economical solution.
some of its special features are and listed below –

High strength at low weight.
Good impact, fatigue, and Tensile Strength (Ultimate)
Excellent environmental resistance.
Excellent chemical and corrosion resistance.
Superior surface finish.
Better life of the entire HVLS fan system due to low assembly weight.
Low moment of inertia help for the selection of optimum motor and reduce over design due to higher starting torque thus motor operate under a better range of efficiency.

Z

Fan Hub / Boss

Hub used in HVLS fans is of heavy in construction. In this, we are using heavy thickness mild steel plate, cast iron or Aluminum clamp and stainless steel hardware. It provides long life, as we coat all mild-steel part with heavy thickness of zinc. Note – Optionally we also customize hub/Boss on demand of the customer, like caste hub boss, Spider Type Fabricated hub, etc.

Key Feature

Heavy-duty MS fabricated.
Hub is dynamically balanced as per ISO 1940 grade 6.3 or 2.5 if required.
The individual part of the hub is moment balanced.
All the MS part are hot-dip galvanized Option for different grades of ss plate is also available.
Nut bolt used are of coated HT or stainless steel series.
For sea weather application Solvent Free, Self-levelling Coatings are available.

Z

Taper Locking

In most of our HVLS fan, we preferred to have a taper locking arrangement. It is a proven part of the easy assembly in the field. These taper lockings made of Cast iron or stainless steel.

AERODYNAMIC HUB

is made of E-glass anti-static fiber, having UV protection, it is available in the segment for ease of transportation.

This hub maintains laminar airflow at the centre of the fan and avoids eddies generation.
It has a high surface finish for smooth airflow.
Anti-static properties to avoid the static charge.
Seals the fan circuit and avoids air recirculation.
With the use of an aerodynamic hub, The designer gets the freedom to reduce the mechanical hub dimension.
