Henley Zephyr Eco Ceiling Fan – Extra Long Extension Drop Rods 200cm – 300cm

Description

Lower Your Ceiling Fan To The Correct Height

Drop rods are often called extension down rods or pipes. They are important as they bring the ceiling fan down to the correct height and also to look good.  The correct and most efficient operation which is about 8ft/2.5m height above floor level, any lower and you risk the safety of tall occupants. The length of the drop rod will be determined by the ceiling type, it’s height and the drop of the fan.  If your ceiling is above 8ft then the use the sizing guide below to see what length of drop rod is needed.  NB:  If your ceiling is lower than 8ft/2.5m then you should use a flush mounted ceiling fan instead of the short drop rod that usually accompanies most ceiling fans.

If your ceiling is above 2.8m/9.2 ft then the length of drop rod that needs to be added will be whatever is needed to keep the fan at a 2.8m/9.2 ft height. A ceiling fan will still work even if it is higher than this but will loose some of its effectiveness which increases as the height increases so you end up with less cooling.

The Zephyr fans come with a short 8″/20cm drop rod included. This can be cut down to a min of 12cm if needed for low ceilings.  We supply standard size drop rods of 60cm and 100cm that are suitable for most needs and available from here.  If you need even larger drop rods then read on.

Wobbling Ceiling Fans

In general, it is advisable to use a solid cross-member for very tall ceilings, pitched rooves or alcoves since very long drop rods will resonate a little bit just like a guitar string.  If a cross-member is not possible or sometimes for aesthetic reasons then longer drop rods can be used as the resonance in negligible and the motor itself will not wobble provided the blades are balanced correctly.   The picture is of a 5m drop rod on a MrKen ceiling fan.  Watch the video of a 3m drop rod that we had custom made and I tested in my garden using a tree that was moving a bit in the wind, notice how the motor itself is not wobbling.

If the fan blades and motor are properly balanced using the balancing kit then there should be no wobble even with a very long 72″/183cm drop rod – it is not uncommon to see wobbling fans even with short drop rods!  Fans placed near the top of a high ceiling or where no drop rods have been used – as seems to be the case in many large retail outlets and airports – are achieving nothing and are a pointless waste of money.

Extra Long Ceiling Fan Drop Rod – Sizing Guide

We have designed our own custom 2m and 3m drop rods made in a local UK top-quality fabricator.  The painted finishes are powder coated/oven baked to give an extra-hard finish.  Custom colours are spray painted on top of the powder coat with synthetic paint.

To facilitate shipping the 3m ones are joined by a welded sleeve that slots over the other one and are secured with a bolt and dome headed nyloc nut. The 2m ones are a single rod that can be shipped.  If you need even longer drop rods then these can be custom made up to 5m – please contact the office for details.

• Lengths – 200cm or 300cm
• Sizes –  Large for regular and Propeller Zephyr and small for the LED version
• Powder coated painted finishes  – Matt or textured matt black, matt white powder coated/oven baked hard finish
• Brushed chrome finish – In 2m only, this is actually a stainless steel rod so better quality as it won’t ever rust
• Extension wiring looms – 4 or 6 wire loom included.  This has snap connectors on the large size but the LED small version needs to be soldered due to the small size of the tube connectors will not fit.
• Receiver – These need a special blue receiver to work in place of the regular one shipped with the fan.  This is included.
• Made in the UK.

In-between sizes – The drop rods can be cut down if required.  Simply drill a new hole for the cotter pin to go into.

Drop Rod Wiring

The wiring loom comprises of 4 wires that run down to the motor via a cable that sits inside of the drop rod.  These carry live, neutral, earth and a control signal.  For the LED version there are two additional wires for the light.   Wherever possible we use the snap connectors to make the connections to the motor and receiver as simple and quick as possible.  For the LED version the rod is a  small diameter approx. 21mm compared to the 27mm diameter of the non-led and not able to accommodate the connector at the bottom so the wires need to be soldered there first during assembly.

Note: – Due to the high handling and shipping costs these sizes are only available as a special orders.  This means that they cannot be returned unless delivered damaged so please double-check you need them before ordering.
