Soler & Palau TD-500/150 3V Duct Fan

Name: Soler & Palau TD-500/150 3V Duct Fan | Seven Star LLC
Brand: Soler & Palau
SKU: TD-500/150 3V

A low-profile duct fan for 150 mm ductwork where ceiling voids are tight

The Soler & Palau TD-500/150 3V is a plastic-cased in-line mixed flow fan that sits directly in a 150 mm circular duct and moves up to 560 m3/h on its highest of three speeds. The S&P datasheet describes the whole TD-MIXVENT range as a low-profile design for installations where installation space is limited, such as false ceilings, and that is the practical reason to choose it over a larger cabinet or centrifugal unit: the casing is slim enough to be hung in a ceiling void next to the duct it serves.

In Gulf building services this size is typically met in toilet and washroom extract risers, small kitchen and pantry extracts, equipment rooms and fit-out zones where a short 150 mm duct branch needs a dedicated booster. The fan is a single-phase 230 V unit with a thermally protected motor, so it can be wired from a local lighting or small-power circuit without a three-phase supply.

This page covers the single motor version coded TD-500/150 3V. The same datasheet row also covers the 160 mm twin (TD-500/160 3V) and timer versions marked T; those are separate order codes, so confirm which one you need on your enquiry.

Features printed in the S&P datasheet

Supplied in tough reinforced plastic casing with an ABS impeller (series construction table).
Support bracket arrangement lets the motor and impeller assembly be fitted or removed without dismantling the adjacent ducting.
Ball bearings greased for life and safety thermal overload protection in the motor; motor protection IP44, insulation class B; protection class II for this size.
Suitable for voltage speed control and fitted for 3-speed connection, with a COM-3 or INTER 4P 3-speed switch and REB-1 or RMB-1,5 speed controller listed against this model.
Can be mounted at any place of the air duct (flexible mounting position).
Performance data stated in accordance with ISO 5801 and AMCA 210-99; the catalogue carries an ErP OK symbol for the range.

Choosing between TD-500 variants and speed options

The datasheet lists TD-500/150 3V and TD-500/160 3V on one row: same speeds, power and 2.7 kg weight, differing only in the duct diameter, 150 or 160 mm. Match the code to the actual duct, so the two are not interchangeable without checking the spigot.

Pick the run-on-timer version if the fan should keep running after the light is switched off. The datasheet states that TD-MIXVENT-T models carry an adjustable timer from 1 to 30 minutes, and that they are not suitable for speed control. Order the plain TD-500/150 3V if you plan to use a 3-speed switch or an electronic regulator.

Size the fan from the speed table. Moving from high to low speed drops airflow from 560 to 390 m3/h (about 30 percent lower, derived) and sound pressure from 35 to 26 dB(A).

Installation and operation notes from the catalogue

Before installation, check that voltage, power and frequency on the data plate match the intended supply; this instruction is printed at the head of the technical table. The mounting method shown in the datasheet runs in four steps: fix the support bracket, place the impeller and motor assembly, carry out the wiring connections, then connect the ducts.

Because the fan can sit anywhere along the duct, no dedicated plenum is needed.

Where it is used in GCC building and industrial services

In Oman and elsewhere in the Gulf the fan suits ceiling-void extract from toilets, janitor rooms, battery and UPS rooms with a modest ventilation need, small electrical rooms and ventilated enclosures. Its printed operating range of -20 to +60 degC covers warm air extracted from plant rooms.

It is not a fire-rated or hazardous-area fan: the datasheet gives no smoke-extraction or ATEX rating for this model, so use another series where those duties apply. For larger duties browse other HVAC and combustion equipment on the site.

Related accessories and companion products

The TD-MIXVENT datasheet pages list the 3-speed switches COM-3 and INTER 4P, the electronic controller REB-1 and the autotransformer type RMB-1,5 against this model. Ventilation kits that bundle flexible aluminium ducting, an interior valve and an exterior grille are catalogued only for the TD-160 and TD-250 sizes, so they do not apply to the TD-500/150 3V.

Frequently asked questions

What airflow does the TD-500/150 3V deliver? The S&P table gives a maximum airflow of 560 m3/h at 2590 rpm, falling to 470 and 390 m3/h on the medium and low speeds.

Is the motor single or three phase? Single phase 230 V, 50/60 Hz, class B, IP44 with thermal overload protection.

What is the maximum air temperature? The datasheet prints -20 to +60 degC for this model.

Does it need a speed controller? No. It can run on a 3-speed switch such as COM-3 or INTER 4P, or on REB-1 or RMB-1,5 for stepless control.

Is Seven Star LLC the manufacturer? No. Seven Star LLC is an independent supplier in Muscat; confirm model, voltage and duct size before ordering.
