You have a 1,000-litre tote of paint, coating or ink, and the amazon.co.uk page already sorts horsepower by thickness. The IB1000L listing, ASIN B0FWRDJ4RL, is priced at £347 in our comparison file. It prints a guide from water-like liquid through to 10,000 centipoise, and it never names which motor is in the box or how much air that motor uses. An IBC agitator air compressor viscosity decision starts with those two blanks. Until a seller names the horsepower and the flow, the table cannot size the compressor.

Peter F. read the UK listing files for that IB1000L, for the generic page B0HLXKCNZ7 at £245.99, and for the MOUNW unit B0CLJDWZ9R at £225.90. This article records those files. It adds no lab mix and recommends no compressor model from a pressure figure. Prices can change on amazon.co.uk. A qualifying purchase through our links can earn a commission at no extra cost to you. The top pick in the agitator comparison is the SZXMDKH ball pack for small bottles, about £5.11. It does not mix a tote.

In short

The only centipoise table in this set sits on the £347 IB1000L page, and it is seller guidance for choosing a motor. The generic £245.99 page lists 1/2 hp, 3/4 hp and 1 hp together, plus a ceiling of 0.6 MPa, without saying which machine you will receive or how many litres per minute it needs. The £225.90 MOUNW page gives neither a pressure nor a viscosity. Until the seller names the motor and the air consumption for the exact ASIN, you cannot size a compressor from the listing.

Viscosity numbers on the IB1000L

The IB1000L is the only page in the set that ties horsepower to thickness. It pairs 1/2 hp with water-like viscosity, 3/4 hp with 1 to 1,000 centipoise, and 1 hp with 1,000 to 10,000 centipoise. One centipoise equals 1 mPa.s. Water sits near 1 mPa.s, and that figure says nothing about your paint. The file contains no timed mix of a named product, so 10,000 cP is the seller's upper label. Treat that label as a menu for motors, then ask which motor this ASIN contains. The box line says only "IBC air agitator". The brand field is empty, and the maker string nanhaiquweiruisi does not fill in the horsepower. A data sheet at 4,000 cP lands in the printed 1 hp band on paper. It describes the carton only after the seller confirms the motor.

The dimensions are the part you can measure. The file gives a 960 mm rod, two folding impellers that open to 250 mm, a rack from 720 mm to 1,200 mm, and a weight of 12 kg. Capacity is stated as 1,000 litres, also written as 265 gallons. Speed is called adjustable, with no rpm. Check the bung and the headroom before you debate centipoise. The agitator buying guide lists what a usable listing should name before you trust a capacity line. A page that withholds the motor has withheld the claim.

Three horsepowers on one listing

The generic listing at £245.99, ASIN B0HLXKCNZ7, model KM-KPzJJO-Multicolor-, prints three machines at once. The bullets name 1/2 hp, 3/4 hp and 1 hp, speed bands of 0 to 1,300, 0 to 1,900 and 0 to 2,500 rpm, and vessel classes of 50, 100 and 250 gallons. They also describe a folding propeller, a clamp, and a stainless rod and blade. The file never joins the ASIN to one motor, one speed or one size. There is no star line and no review text.

A three-horsepower bullet is a menu. If your liquid sits in the upper band shown on the IB1000L, this page has not promised the 1 hp motor. If your tote is a 1,000-litre cage, the page has not said the 250-gallon variant will arrive, and it has not equated those gallon classes to 1,000 litres. The IB1000L is the listing that states 1,000 litres. Borrowing its viscosity table for the cheaper ASIN stacks two unknowns. Ask, in writing, for one configuration: horsepower, rpm band, vessel size, air consumption and maximum inlet pressure. A price under £347 saves money when the carton matches the motor you sized. The clamp describes the mount, and the file gives no stainless grade.

Air pressure with no flow figure

The generic bullets say up to 0.6 MPa. That is 6 bar, about 87 psi if your gauge is marked both ways. The IB1000L states no pressure and tells you to supply the air. The MOUNW page states neither pressure nor viscosity. An air motor needs a volume of air each minute at a working pressure, in litres per minute or cubic feet per minute. Neither B0HLXKCNZ7 nor B0FWRDJ4RL gives that volume. HSE publication INDG178 places receiver duties with the compressed-air system, and these mixer pages specify no receiver, hose bore or filter. Turning 0.6 MPa into a compressor model, a tank size or a duty cycle would invent a flow the seller left out.

The usual failure is a gauge that reaches the stated bar while the motor bogs as receiver pressure falls. The IB1000L lists the 960 mm rod, the 250 mm blades and the 12 kg weight, and it stays silent on consumption. If a seller later quotes a flow, tie it to this motor, to a pressure in bar, and to the two folding impellers. A lone cfm figure, or a figure borrowed from the 1 hp version, still leaves the carton unknown.

The compressor and the zone stay with you

The mixer and the air system are separate purchases. The IB1000L contents line is the agitator. The generic page expects compressed air and withholds the flow. The MOUNW, model dd0237001222, is £225.90 in the file, scored 4.6 from three ratings, with no review text. The title aims at a one-ton IBC and at paint, coatings and ink. The bullets stop at foldable and portable. Three ratings do not describe a thick liquid in a full tote, and the page still omits pressure, speed and air volume.

An air motor takes the mains motor off the lid. HSE guidance on explosive atmospheres still applies where the product can create one. The generic page says the pneumatic design is particularly suitable for flammable and explosive industrial environments, and the file contains no certificate number. Treat the sentence as seller copy. The pneumatic and electric comparison explains why that line cannot stand in for a workplace assessment. If you already run a receiver, INDG178 keeps the written scheme of examination with that system. A new air tool does not rewrite the scheme, and the carton does not include one. Get consumption in writing before you buy a compressor for this tote. None of the three files gives a run time or a cleaning method. Take those from the liquid supplier and from how the tote is bunded and vented.

What to ask before you pay

Ask these before you pay £347, and wait for answers that name ASIN B0FWRDJ4RL.

  1. Ask which single horsepower is packed with this ASIN, and which printed centipoise band that motor is meant to cover.
  2. Ask for litres per minute at a stated pressure for that motor. Leave the 0.6 MPa line on B0HLXKCNZ7, where it is printed.
  3. Ask for the maximum inlet pressure of the supplied motor. The IB1000L file does not state one.
  4. Ask for shaft speed in rpm, or for a plain statement that speed is unspecified.
  5. Ask whether an explosive-atmosphere certificate applies, and for the number if the seller says yes.
  6. Check the 960 mm rod, the 250 mm open blades and the 720 to 1,200 mm rack against the cage, bung and headroom.

Use the same list on the £245.99 page, and ask which gallon class and which speed band ships. A reply that still offers 1,300, 1,900 and 2,500 rpm has not chosen a machine. The MOUNW page needs pressure, viscosity and flow from a datasheet. File the answers with the order. If the seller cannot name the horsepower, you would be buying a 1,000-litre mixer from a shaft length and a price. Return to the buying guide for the wider checklist before the tote is full.

Common questions

What viscosity numbers are on the page?
The IB1000L listing, ASIN B0FWRDJ4RL, is the only page in this set with a centipoise guide. It pairs 1/2 hp with water-like viscosity, 3/4 hp with about 1 to 1,000 cP, and 1 hp with about 1,000 to 10,000 cP. One centipoise equals 1 mPa.s, and water sits near 1 mPa.s. That water figure is a unit reference. The file does not record a timed mix of a named paint, ink or coating, so 10,000 cP remains seller guidance rather than a measured result on a full 1,000-litre tote.
Which horsepower will I receive?
The IB1000L file does not say. The guide mentions 1/2 hp, 3/4 hp and 1 hp, and the box contents line only says IBC air agitator. The generic listing B0HLXKCNZ7 prints the same three horsepowers beside three speed bands and three gallon classes, without tying the ASIN to one of them. Ask the seller for the horsepower packed with the exact ASIN. A reply that repeats the whole menu still leaves the motor unknown.
What air pressure is stated, and where is the flow?
Only the generic page B0HLXKCNZ7 states a pressure, and it states a ceiling of 0.6 MPa, which is 6 bar or about 87 psi. The IB1000L tells you to supply the compressor and gives no pressure. The MOUNW page gives neither pressure nor viscosity. None of the three files states litres per minute or cubic feet per minute. A pressure figure describes a limit on the gauge. It does not tell you the volume of air the motor needs.
Is 0.6 MPa the same as a compressor I can buy?
0.6 MPa is a pressure, equal to 6 bar. It appears as an upper figure on the generic multi-model listing, and that listing still does not identify the motor. A compressor you can buy is a machine with a stated free-air delivery, a receiver and a duty. Those flow figures are absent here. HSE publication INDG178 places receiver duties with the compressed-air system you supply. Matching a shelf model to 0.6 MPa alone would invent a size the pages do not give.
Does the MOUNW listing answer any of this?
The MOUNW page, ASIN B0CLJDWZ9R, model dd0237001222, is priced at £225.90 in the file and scores 4.6 from three ratings, with no review text stored. The title points at a one-ton IBC and at paint, coatings and ink. The feature lines stop at foldable and portable. Pressure, horsepower, speed, viscosity and air consumption are absent. Three ratings do not describe how the blade behaved in a full tote. You would need a separate datasheet before this page could size a compressor.
Does an air motor skip DSEAR?
An air motor takes the mains motor off the vessel. It leaves the liquid, the vapour and the workplace assessment where they are. HSE guidance on explosive atmospheres still applies if the product can create a dangerous atmosphere. The generic listing says the pneumatic design is particularly suitable for flammable environments, and the file contains no certificate number. Treat that line as seller copy. Confirm any marking in writing, and keep the zone decision with the workplace rather than with the Amazon bullet.
What should I ask before paying £347?
Ask which horsepower is packed with B0FWRDJ4RL and which printed viscosity band that motor is meant to cover. Ask for air consumption in litres per minute at a stated pressure, and for the maximum inlet pressure of that motor. The 0.6 MPa line belongs to the other listing. Ask for shaft speed in rpm. Ask for any explosive-atmosphere certificate number. Then check the 960 mm rod, the 250 mm open blades and the 720 to 1,200 mm rack against your cage and bung. Keep the written answers with the order.
