350 Litre (75 gallons) Baffled Window Cleaning Water Tank.

Product Overview

The 350 Litre Baffled Upright Water Tank is a robust and practical solution for the storage and transportation of potable water and a wide range of other compatible liquids.

Manufactured from durable MDPE / polyethylene, this upright tank provides a nominal capacity of 350 litres, equivalent to approximately 75 gallons. Its upright configuration provides a useful combination of substantial storage capacity and a relatively compact footprint, making it particularly suitable for vehicle-based and above-ground applications.

The integrated baffle system is designed to reduce the movement of water within the tank during transportation. This makes the tank particularly well suited to mobile applications such as window cleaning, car valeting, vehicle cleaning and other situations where water needs to be transported safely.

The tank is supplied with a 1" BSP female outlet and a 6" vented lid with an opening of approximately 115 mm. The natural translucent MDPE construction also allows the approximate water level to be viewed through the tank.

Upright & Space-Efficient Design

The 350 Litre Baffled Upright Water Tank has been designed to provide substantial water storage capacity while maintaining a practical footprint.

Measuring approximately 520 mm wide, 990 mm long and 750 mm high, its upright configuration makes effective use of available space while providing 350 litres of nominal storage capacity.

The tank is particularly useful for vehicle-based installations, mobile cleaning systems and other applications where water needs to be stored and transported.

Potential applications include:

  • Window cleaning
  • Car valeting
  • Mobile vehicle cleaning
  • Mobile pressure washing
  • Commercial cleaning
  • Potable water storage
  • Portable water supplies
  • Agricultural applications
  • Horticulture
  • Irrigation
  • Site water storage
  • General-purpose liquid storage

The tank should be installed on a suitable, stable and adequately supported surface.

Integrated Baffle System

One of the key features of this tank is its integrated internal baffle system.

The baffles are formed through the tank using grooves and openings that interrupt the movement of liquid. Their purpose is to reduce the amount of water that can move from side to side when the tank is being transported.

This makes the tank particularly suitable for mobile applications where water needs to be carried inside a vehicle.

The reduced liquid movement can help provide a more stable load during transportation, although the baffles do not eliminate water movement completely. The tank must therefore be properly installed and securely restrained before transportation.

It is important to note that the internal baffle design reduces the usable capacity of the tank.

Ideal for Window Cleaning & Car Valeting

The 350 litre capacity makes this tank particularly suitable for professional cleaning applications where a substantial quantity of water needs to be transported.

Typical users include:

  • Window cleaners
  • Car valeters
  • Mobile vehicle cleaning companies
  • Pressure washing businesses
  • Commercial cleaning contractors
  • Mobile cleaning operators

The combination of an upright design and internal baffling makes it a practical choice for vehicles where water needs to be transported to different locations.

Applications

The 350 Litre Baffled Upright Water Tank is suitable for a wide range of domestic, commercial and mobile applications.

Typical uses include:

  • Window cleaning
  • Car valeting
  • Mobile vehicle cleaning
  • Mobile pressure washing
  • Commercial cleaning
  • Potable water storage
  • Portable water supply
  • Agricultural applications
  • Horticulture
  • Irrigation
  • Site water storage
  • Vehicle-based water systems
  • General-purpose liquid storage

Its internal baffling makes it especially suitable for applications where water needs to be transported by road.

Overseas orders

International orders are welcome. Payment is by IBAN / SWIFT / BIC, MoneyGram and letters of credit. We regret that credit cards are not accepted for international orders.

A purchase order is required; we will then create a pro-forma invoice, and tanks are ordered on clearance of funds.

If you require additional export documentation — for example a Certificate of Origin, or commercial invoices certified by the Chamber of Commerce — you must notify us before completion of your order, as we will have to invoice cost and admin charges to the order.
