Product Description

This stainless steel tank gives the added strength, working lifespan and increased maximum working pressure when compared to plastic tanks. You have a choice of sprayers within the Plus range so select from either 6 or 10 litre which allows you to have the size that best suits your requirements.

This range of stainless steel compression sprayers are ideal when working in areas where they may be subjected to a little more rough & tumble which makes them ideal for the professional user. So if you are planning to have them in & out of vans or use them on building sites or if they are going to be used by multiple people then the added strength of the steel tank will be a real bonus. In addition to this, the steel tank allows for a higher maximum working pressure of 6 bar compared to the 3 bar of a plastic tank and the steel can handle higher liquid temperatures than plastic.

Whilst this prayer is fitted with FPM seals it does not mean that it can be used to spray all types of acidic chemical. We therefore recommend a compatibility test when using aggressive chemical solutions. If you think there may be an issue with a product that you wish to use then just send us the safety data sheet (MSDS) for the product and we will check compatibility and recommend an alternative sprayer if necessary.

Why is the tank size different from the working capacity?

With compression sprayers you must have room, within the tank, to pressurise air which will then push the liquid out of the tank. This is why there is a difference and this difference is called ullage. This sprayer has a 13-litre tank but we recommend a maximum fill of 10-litres which gives an ullage of 3-litres which you pressurise when you pump the compression handle. The more pressurised air that there is within the tank then the longer spray time between stopping and re-pressurising the tank. Be careful when buying sprayers as you need to know the fill volume/capacity not the tank size.

Why should I use a Stainless Steel sprayer?

They are strong, look very good, are robust and give very good chemical resistance when used in conjunction with the FPM seals. If you are trying to decide whether a stainless steel tank or a steel tank is the best option for you, the main difference is that the steel tanks are painted to protect the steel from the housed liquids. This means that if the internal paint is damaged, maybe the tank has been dented, then the hosed liquid can get in contact with the steel and start to corrode the tank. Basically, stainless steel tanks should have a longer lifespan than steel tanks.

You say that this sprayer can be used at 6 BAR, how do I know when it is at pressure?

The Ferrox Plus sprayers have a pressure gauge fitted which will show you the air pressure within the tank. This is very helpful as sometimes you will just want the most pressure possible especially if you are trying to spray a very thick liquid but some products will recommend a spraying pressure for optimum performance. With the gauge you can see exactly the pressure that you are spraying.
