Working capacity of 4430 ml from a 5540 ml tank, this TEC 5 sprayer runs on manual pressure up to 3 bar. The black EPDM seal keeps joints tight when handling compatible chemicals. A 110° fan nozzle, 40.5 cm lance and 1.4 m hose extend reach. The safety valve releases excess pressure automatically. An adjustable 120 cm shoulder strap supports longer spraying sessions.
The 5 litre chemical sprayer with EPDM seal, sold as the EPOCA TEC 5, carries 4430 ml of working liquid. The tank itself holds 5540 ml nominal volume. Pressure is built up manually and capped at 3 bar. A pressure safety valve vents automatically once that limit is passed. The black EPDM gasket set defines which chemicals the unit can handle.
Spraying runs through a nozzle with a 110° fan pattern. The plastic lance adds 40.5 cm of reach, and the hose another 1.4 m. A detachable spray handle lets the operator work away from the tank. The reinforced PP pump shaft carries the stroke load. A stability base keeps the tank upright on floors and benches. The shoulder strap adjusts up to 120 cm for walking jobs.
Pressure comes from a hand pump mounted in the tank lid. The pump shaft uses reinforced PP, a material chosen to resist the chemicals held inside. Operating pressure is limited to 3 bar. Beyond that figure, the safety valve opens and bleeds the tank. The wide stability base lowers the chance of tipping when the unit stands on a workshop floor.
Refills are less frequent than with small one litre units, which suits continuous cleaning rounds. Operators pump to pressure, spray, then repeat as the pressure drops. Releasing the safety valve before opening the lid keeps the refill step controlled. Store the tank empty and depressurised when work ends, and rinse it after each chemical change.
The black EPDM gasket set handles the chemical families compatible with that elastomer. Two sister versions exist with Viton and NBR seals, so the gasket material decides the model choice. The nozzle sprays a 110° fan pattern, useful for covering surfaces rather than point targets. A 1.4 m hose and a 40.5 cm lance put the jet where the hand cannot easily reach.
Check the gasket, hose and lance threads at regular intervals. Worn seals cause pressure loss and dripping at the lance connection. Clean the nozzle with water after use so the fan pattern stays even. The shoulder strap shifts the load from the hand to the body, which helps when moving between machines or across a yard.
The TEC 5 suits tasks that need volume and reach rather than short touch-ups. Typical uses include surface cleaning in workshops, applying detergent to vehicle bodies and wheels, and treating floors or equipment with EPDM-compatible solutions. Agricultural and greenhouse spraying also fits, where the operator walks between rows. The strap and hose combination allows spraying at a distance from the tank, including under machines and into corners.
Catalogue listings identify this version as TEC 5 with EPDM sealing and black cap, catalogue reference 7684.S001. The related sprayers in the same family share the 5540 ml body but differ in gasket material: a Viton variant with blue-black cap, and an NBR variant with red-black cap. Select the seal according to the chemical you intend to spray, then match the accessories listed above.
