Energy-efficient power-saving Maya Tea withering fan:

Introduction – WITHERING is the first and foremost steps involved in tea manufacture. The evaporation of moisture in the green leaf brought about by blowing or moving air over tea leaf in the withering trough. The current of air performs two functions. Conveying heat from tea leaf as well as carrying away the water vapour through a bed of green leaves. Whenever the hygrometric difference below 3° C hot air mixed in a suitable proportion. But the dry bulb temperature of the air after mixing should not exceed 35° C.

Considering all the above need and operating conduction. MAYA fan develops a series specially dedicated for Tea withering fan.

FRP tea withering fans

Conventionally tea withering fan manufactured with impellers made of aluminium or mild steel. The grey area today is dimensional and surface finish stability of the metallic impellers. In fan blade, profile and its finish are most sensitive for the efficiency of the fan. And because of corrosion on the metallic blade profile resistance for the flowing air increase. This leads to high power consumption & high noise levels with lesser efficiency.
Therefore Introduction of fibreglass composite material. And ease of processing Help designer of withering fans to adopt more efficient profiles. Optimum distribution of fan blade chord and twist is difficult to generate in the metal blade. Owing to this fact hollow FRP bladed fans are being rapidly adopted for tea withering applications.



Up to 40% power saving




FRP Tea wethering fan has the following advantage-

Reduction in the weight of FRP fan assembly provides extended life of a mechanical drive system.

Low power consumption resulting in appreciable energy savings.

Ease of FRP fan handling and maintenance.

Lower flow noise and mechanical noise levels compared to conventional metallic fans.

FRP fan has excellent corrosion and erosion resistance.

Zero Cost Solution for power saving opportunity.

Why choose Maya Tea Withering fan?

Low Operating Costs

  • Maya High efficient airfoil blade design.

  • Optimization of twist cord and cross-section provide maximum efficiency.

  • The involvement of advanced composite material. It reduces turbulence and produces smooth linear airflow.

  • Best design for the duty point No overdesign 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. For most demanding heavy industrial applications while still delivering an outstanding value.
  • Lightweight impeller, thus, increases in the life of all the mechanical components.
  • Tea withering fans are also available with Series 300 stainless steel as an optional upgrade. This comes with a 5-year limited warranty.
  • Maya Tea withering Fans manufactured in ISO-2015 certified facilities.

Fast emergency response.

  • Ready-made fan available.
  • The minimum stock of the fan spare maintained.
  • Low manufacturing leads to time because of zero outsourcing.
  • The 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 proportional to tip speed).
  • No outsourcing full quality control thus achieves minimum 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 and to maintain its performance despite critical variation in weather. Maya tea withering fans designed for a broad range of operation. Our fan having a reserve margin for both airflow and static pressure. And this help fan to deliver performance throughout the year in all type of seasons.

Low Maintenance/Less Downtime

 Maya FRP Tea withering fans made of high-quality material and robust design.

Maya design fans for low operating tip speed which increases system life and also reduces the chance of failure.

Unlike painted fans. We do provide a permanent coating of a gel coat that remains an integral part of the fan blade. And does not get separated due to erosion.

FRP Tea Withering fan construction

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


Fan Blade

Maya Tea Withering fan blade made of the latest airfoil. These are similar to an aeroplane wing. We do choose the most advanced airfoil possible for the fan to provide maximum efficiency. And we achieved superior performance. Our blade is very robust in construction and designed for 7-10 times of operating load. We also provide superior wear resistance material to maintain surface stability.

This FRP Tea Withering fan blade is having some of the very charismatic property. It is very much possible to produce any complicated shape with ease. Thus provide 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 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 operates under a better range of efficiency.

Fan Hub / Boss

Hub used in Tea Withering fans is heavy in construction. We are using heavy thickness mild steel plate, cast iron, or Aluminum clamp and stainless steel hardware to provide long life. We are coating all mild-steel part with heavy thickness of zinc. Note – Optionally we also provide customize hub/Boss on special 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.

Taper Locking

in most of our fan, we preferred to have a taper locking arrangement which is proven in the field these taper lockings are mostly made of Cast iron or stainless steel.



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

  • This used to maintain laminar airflow at the centre of the fan and avoid eddies generation.
  • It is having a high surface finish for smooth airflow.
  • It is having anti-static properties.
  • It seals the fan circuit and avoids air recirculation.
  • It gave freedom to reduce the mechanical hub dimension.

Frequently Asked Question

Why Tea Withering fan replacement cost is high ?

The old casted fan just comes at the rate of casting whereas FRP fan needed very much effort. Though the initial cost may be higher. But with these improved tea withering fan operating cost will reduce very much. We can achieve up to 3-10 month payback period.
