Interfold panel filters are a cardboard disposable filter that offers effective pre-filters for nearly any HVAC system. The Interfold is designed to be a disposable cardboard pre-filter, consisting of a high wet-strength beverage board and a synthetic filter media that is laminated, wire-backed and pleated in a unique super-vee pleat design that is designed to provide optimal air flow characteristics and low pressure-drop.
The interfold cardboard panel filter is available in efficiencies ranging from G4 through to F9 using specialised material; varying pleat depths of 25, 50 and 100mm and a range of standard and non-standard sizes are available.
We produce our Interfold range in several locations: Sydney, Adelaide, Perth, Thailand and the UK. Due to the high cost of importing and moving basic Air Filters around the world, it is a far more sustainable solution to create small manufacturing cells in each location that we operate from. This provides local jobs, it reduces lead-times for customers and allows for tailored solutions in each area.
The Interfold range is manufactured using Australian sourced materials. The pulp used to produce the cardboard frames is a kraft board with a high wet-strength designed for durability in harsh Australian conditions.
The achievement of indoor air quality is a function of system design, filtration selection and maintenance as described in Australian Standard AS3666. Contaminated heating and cooling coils have heating/cooling transfer efficiency reductions of up to 25% when a coating of 1mm of dust is collected on the coil surface. The Interfold filter aids indoor air quality by providing an effective filtration solution and a desirable cost-point. The Interfold will often be paired with an Inter-pocket Bag Filter in a combination or staggered filter arrangement in what is the most common arrangement for Air Filters within general HVAC applications.
A simple retro-fit can upgrade any new or existing air filtration system to incorporate AES Environmental’s Interfold. The high dust holding capacity extends replacement intervals, and used as a prefilter, considerably lengthens the service life of other secondary filters in the system. AES Environmental Interfold is suitable for air conditioning and industrial applications, the range can be supplied in standard air conditioning HVAC industry sizes or can be customised to suit unique applications.
The AES Environmental operates a NATA accredited on-site filter testing laboratory. The Interfold range is tested to AS 1324 using our in-house test facilities and meets the requirements of ISO 16890.
