Schego Prima Air Filter Felt (5pcs)

Description

Schego Prima Air Filter Felt (5pcs) — Five replacement prefilter felts for the Schego Prima air pump

A felt pad the size of a coin is all that stands between room dust and the working parts of an air pump. Schego Prima Air Filter Felt (5pcs) (SKU: SH734) is a pack of five replacement filter felts for the Schego Prima diaphragm pump, listed as item 734 in Schego’s parts list for the Prima. In Schego’s instructions the prefilter sits in the base plate of the pump, and the instruction is to replace it regularly when it is dirty. Left in place too long, it chokes the intake, and the pump’s output falls even though the motor and diaphragm are fine.

The Prima is a 100 L/h pump, 110 L/h with no head, drawing 3 W according to retailer specifications, with a case of about 116 × 66 × 51 mm and no flow adjustment. It is made for indoor use at 220–240 V and 50 Hz. Because there is no regulator to turn, a gradual loss of airflow is easy to mistake for a failing pump; looking at the felt first costs nothing. Five pieces in a pack covers a long run of changes for one pump, or several pumps in a small fish room. A grey, matted or visibly dusty felt should be replaced, and the diaphragm set (SH731) is the next suspect if airflow stays low with a fresh felt. The maker and supplier do not publish felt dimensions, so the old pad is the guide to how the new one sits.

Usage & Application

When to Use

• Dirty prefilter: Schego’s trigger for replacement is a felt that has become dirty.
• Airflow slipping: The first check when a Prima’s bubbling weakens.
• Multiple Prima pumps: Five pieces cover a rack of small tanks.
• Dusty positions: Pumps on floors, shelves or in sheds clog sooner than ones in clean rooms.

Installation & Replacement Guide

• Unplug first: Disconnect the mains plug and the airline.
• Find the base plate: The prefilter sits in the base plate of the pump.
• Replace the felt: Remove the dirty pad and lay a new one in the same place.
• Restart and observe: Reconnect the airline and check that the bubbling has returned.
