Pascal Box 4B (4 Ball Capacity) Pressure Ball Charger

Tennis balls are made with an internal pressure of 14 PSI and packaged in a pressurised can. Pressure is released when you open the can. Once this occurs pressure inside the ball will now escape through its porous rubber. During play each time you hit the ball it will force the internal pressure even more. Please note that for effective pressure regeneration within the tennis ball, the surrounding pressure in the device must be greater than or equal to 29 PSI.

PASCAL BOX^® 4B is designed to recharge the regulation pressure of padel, tennis and frontenis balls, achieving the same pressure as the first day. It is made of high quality polycarbonate and can hold 4 padel or tennis balls and up to 5 frontenis balls.

• PASCAL BOX is the only system capable of recovering the regulatory pressure time after time, obtaining a life span of more than 30 matches for your balls
• HIGH PRECISION MANOMETER which allows you to regulate the pressure according to game style and external conditions (temperature, humidity, altitude)
• ALL-IN-ONE System: High resistance container and lid, high precision manometer for adjusting the desired pressure, universal inflate valve, security valve and pump.
• Enjoy the BEST PLAYING Experience always, avoid injuries, safe money, buy smart and contribute to the environmental sustainability.

Over time and with every match the balls lose pressure. Other devices only get to slightly slow this process.

Only PASCAL BOX® recharges the ball to its regulatory pressure, match after match.

Science at the service of Sport.

Pascal Box is the only device capable of keeping indefinitely a 48 PSI pressure. This high pressure transfer into the ball allowing the ball to recover its first day’s bounce.
