This machine is used to test the bursting strength of the Filter Paper / Element

• Test Paper (Filter Element) is put on a Holding Station and clamped from the top.
• From the bottom of the Holding Station, a Diaphragm is pressurized which presses against the Test Paper / Filter Element.
• The Diaphragm is pressurized by Glycerin filled in a container which is pushed by a moving Piston actuated mechanically.
• The load at which the paper fails(bursts) against the expanding Diaphragm is noted through Double Needle Manual Dial gauge.

Dauji rotary pleaters are customized for specific filters sizes and media and enable high speed filters pleat production of desired profiles. Pleat lock designs and dimple forming machines are available with the flexibility of easily modifying pleat depth by using rollers of various diameters.

This machine is used to paste or bond pre-molded plastic discs (end caps) to the filter media by application of heat and pneumatic pressure.

The pre-molded plastic disc is softened on a table top die by applying heat to it through a retractable heater (actuated through a pneumatic cylinder kept underneath the table) for a pre-set time of about 5 10 seconds.

Thereafter the filter media is put over the disc and a pressure is applied from the top through pneumatic cylinder for bonding of the end disc/cap with the filter media.

The salient features of this machine are:

• Provided with double pasting heads so that at a time both the top and bottom plastic discs can be bonded to the pleated media at either of the stations.
• Movement of the top Pressurizing Plate is through Pneumatic Cylinders
• Bottom disc holding die heads are fixed and are insulated to prevent heat loss.
• Pneumatic system is complete with all the regulating arrangements like Pressure Regulator, Pressure Gauge, Safety Valve, FRL unit with Air Release Valve etc.
• The heating cycle, temperature, timing and movement of the cylinders are all controlled through smart PLC based system.
• Provided with smart touch screen-HMI Control Panel.
• Standard table size is 610mm (L) x 700mm (W) x 750mm (H). However this size can vary based on customer requirement.
• Utilizes heat load of up to 6 KW.

This machine is used to bind the filter media with the end cap after adhesive is poured over it. Two Hot Plates-one at the top and the other at the bottom press the assembly electro-pneumatically and the adhesive gets bonded to the end cap/filter media and support tube due to heat.

The salient features of this Hot Plate are

• Movement of the top Hot Plate is through Pneumatic Cylinders
• Bottom Hot Plate is fixed and insulated to prevent heat loss.
• Pneumatic system is complete with all the regulating arrangements like Pressure Regulator, Pressure Gauge, Safety Valve, FRL unit with Air Release Valve etc.
• Provided with Pre-set Timer and Buzzer to indicate the completion of heating cycle.
• Provided with auto cut-off system to stop the machine on reaching the heating cycle.
• Provided with Digital Temperature Display and Controller.
• Top Plate can retract automatically on completion of heating cycle through PLC based control system
• Standard table size is 500mm (L) x 600mm (W) x 750mm (H). However this size can vary based on customer requirement.
• Utilizes heat load of up to 6 KW.

This testing machine is used to test the bonding strength of the End Caps with the filter element.

• The complete filter assembly is put in between Holding Discs inside the testing fixture.
• The End Caps are clamped on the Holding Discs.
• While the top Disc is stationary, the bottom Holding Disc is pulled down.
• Reading is noted on a Double Needle Manual Dial Gauge when the bonding of either of the End Caps breaks off.

This testing unit checks the air flow capacity, life efficiency, dust holding capacity and other parameters of Air Filters as per ARAMCO and ASHRAE standard.

• Can be used to test both Automobile Air Filter and Industrial Air filter.
• Air Blower capacity = 2000CFM(for Automobile Air Filter)

3000CFM (for Industrial Air Filter)

• Static Pressure = 15 Water Gauge

• Motor capacity = 15HP (for Automobile Air Filter)

60HP (for Industrial Air Filter)

• Air Duct Line = 200mm (for Automobile Air Filter)

400mm (for Industrial Air Filter)

• Provided with Butterfly Valve, Dust Feeder, Orifice Plate, In-line Filter, Water Manometers and other requirement as per test standards.
• Provided with automatic back-flashing system with Solenoid valves.
• Can be provided with either one filter mounting system or six filter mounting system.
