Pressure sand filters are suitable in use for the treatment of swimming pool water. These filters use graded sand as the filter medium in circular steel or glass-reinforced plastic tanks. These vary in size from small single units for private house pools to a battery of large units for public pools. There are two types, vertical downward flow, and horizontal. The degree of filtration depends on the grain size of the sand used in the filter and this in turn is a function of the filtration rate used in the filter vessel.
Pressure Senders are available with sealed integrated connectors. The connector assures a weather tight fit for a reliable electric connection and easy installation. These are trimmed by computer-guided lasers for greater accuracy. The thick film pressure senders will last up to five times longer than senders with wire-wound resistors.
Pressure Sensitive Carton Sealing Tapes are general-purpose carton sealing tape specifically designed for use on light-weight cartons and packages that will be exposed to minimal handling and stress. It is perfect for the moving and storage industry and light-duty, general purpose packaging. It also provides low-cost protection for labels and routing slips.
