The Constru Plus 7 compression sprayer has a 5-litre working capacity tank and a 3 BAR maximum spraying pressure.
The sprayer is packaged in a printed cardboard box with plenty of informative photos and basic information regarding sprayer usage and box contents. The box could possibly be a little stronger but seems perfectly ample to both hold and give protection to the sprayer.
Upon opening the box, I found everything to be nicely packed with a sealed bag containing hoses, shoulder strap and spare nozzle placed over the top of the sprayer. I removed this bag and removed the loose items that were packed around the sprayer tank; another plastic bag containing nozzles and two lances, instruction booklet, a third sprayer lance and finally the lever handle. The instruction manual seems to give all the information required, including an exploded diagram giving part numbers should you require any replacement parts. There is also plenty of information telling you how to set up the sprayer which is given in four, easy to follow, steps. There is also maintenance information and some legal bits and pieces.
After reading through the four ‘set up’ steps I found putting the sprayer together to be very easy as all that you really do is connect the hose to the base of the tank then to the lever handle. The lances then join the lever handle and you are ready to spray. The Constru Plus has two rigid lances which can give you a maximum length of around 700mm and a third ‘flexible’ lance that gives you the ability to spray at angles meaning that you could spray on top of items or around corners. This is one of the really very good things with this sprayer and another is that you have a separate hose for acidic products and for oils or fuels. This is good as it allows you to safely use the sprayer with a wide range of chemicals.
Once everything was assembled I was ready to start spraying so I placed the tank on the floor and turned the tank handle anticlockwise and after a few turns pulled the central housing from the tank which allowed me to start filling. The design incorporates a nice wide filling neck so spillages should be easy to keep to a minimum. I managed to fill the tank with no issues, replaced the housing and gently tightened it. I pumped the tank handle around 20 times to bring it to full pressure and spraying was just as I would expect; a nice spray pattern was easily maintained. To release the pressure within the tank simply pull the small, black pressure release valve.
Fully draining the tank was easy as the hose is attached at the base so, if you wish, you can simply unscrew the hose and the tank will fully drain. I would only do this to empty the smallest amount as to empty the tank normally you should remove the central housing (as you did when filling) and pour out the tank contents.
I feel that the Constru Plus is an extremely good option when you are deciding which sprayer you should buy and has obviously been made with the construction industry in mind. The tank size and shape make it able to withstand some serious ‘rough handling’ and the hose option and range of lances including the flexible lance give the user many spraying options.
