The Maxi-Filtra™

March 2005

The new Maxi-Filtra™ is an active carbon filter designed to eliminate bad odours produced by drainage systems, for use externally, it operates as a 2-way vent, filtering air in both directions.

Particularly for use with septic tanks and other outside installations, the Maxi-Filtra™ may also be installed on open vents. Fitting 90mm without the supplied connector and 75mm/110mm with, the Maxi-Filtra™ can be retrofitted onto an existing drainage system to solve problems.

The Maxi-Filtra™ is commonly installed vertically or horizontally with a push-fit connector. The cap simply lifts off to enable easy access for the carbon filter to be replaced. The Maxi-Filtra™ is resistant to adverse weather, requires no maintenance and reduces costs by eliminating the need for odour reducing additives in septic tank installations.

The Maxi-Filtra™ will be available worldwide through the network of distributors from April 2005, following the launch at ISH in Frankfurt. For more information click here.

KEYMARK Accreditation for Products

November 2003

– the world market leader in the area of Air Admittance Valves (AAVs) - announced that on 12 November 2003 DIN CERTCO, Berlin, Germany certified that the AAVs for drainage systems of the types:

Maxi-Vent, KNITS II, OsmaVent 110
Mini-Vent, Mini-KNITS, OsmaVent 40
 
conform to DIN EN 12380:2003-03
 
and granted the licence to use the marks:

KEYMARK & DIN Geprüft

 
The validity of the use of the CE Mark is thereby confirmed by DIN CERTCO.

The KEYMARK is a European quality mark and product certification scheme issued by the European Standard Organisation CEN and empowered by DIN CERTCO - the certification organisation of DIN, the German Institute for Standardisation. The KEYMARK may only be issued after a DIN Geprüft Mark has been issued. It proves that the products fully comply with European Standard EN 12380:2003 through independent auditing by DIN CERTCO.

The DIN Geprüft Mark is the German national certification mark of DIN CERTCO, who issues it when a product is proven to fully comply with EN 12380:2003; through a DIN CERTCO approved laboratory for Initial Type Testing (ITT). Factory production control is inspected by DIN CERTCO, who also carries out full periodic surveillance.

The CE Mark applied to a product is self-certification by the manufacturer that the product fulfils the essential requirements of EN 12380:2003. In most cases, there is no requirement for independent validation of certification. The KEYMARK certification, however, confirms that the products listed above do indeed fulfil the full requirements of EN 12380:2003.

EN 12380:2003 details the requirements for the manufacturer, the test methods and the evaluation of conformity for AAVs to be used in drainage systems installed within buildings in accordance with European Standard EN 12056-2. It sets the performance requirements for AAVs and how the manufacturer should demonstrate compliance with the Standard. Contained within EN 12380:2003 is a table which classifies AAVs based on their performance – ranging from AI as the highest classification to BIII as the lowest classification.

As well as the DIN CERTCO Certificate, was also recently awarded the new British Board of Agrément (BBA) Certificate No 89/2139 (second issue), which also includes the requirements of EN 12380:2003. 

The BBA is an organisation partnered with the United Kingdom (UK) Government to provide authoritative and independent information on the performance of building products within the whole of the UK (England, Wales, Scotland and Northern Ireland). The BBA is the UK member of the European Union of Agrément (UEAtc), representing the UK in the European Organisation for Technical Approvals, and is responsible for the issue of European Technical Approvals in the UK. The BBA Certificate provides data on durability, installation and compliance with UK Building Regulations. Assessment involves laboratory testing, site inspections and factory production control.

The Combi-Siphon™ plus

March 2003

The new Combi-Siphon plus is a trap with a 50mm water seal, combined with an integral Air Admittance Valve, reducing the need for secondary ventilation. Conforming to the requirements of the new European Standard EN12380, this product is ideal for venting small groups of appliances and problem solving in existing buildings.

The Combi-Siphon plus replaces conventional S and P traps and is very easy to maintain - the base simply screws off. Available first in a white ABS version, and later also in chrome, its compact form allows installation in almost every situation.

As a one-way valve, the Combi-Siphon plus allows room air into the waste system when a siphonage action occurs in the discharge pipe. The product is available with 32mm and 40mmm appliance connections.

The revolutionary P.A.P.A.™

Fed up with having to design your drainage systems with open vent pipes? Worried that your design of the drainage system is going to suffer from positive and negative pressure problems?

is pleased to announce the launch of its revolutionary P.A.P.A., the perfect compliment to their existing range of Air Admittance Valves (AAVs).

The P.A.P.A. (Positive Air Pressure Attenuator) has taken several years to develop by Professor John Swaffield and Dr David Campbell of Heriot-Watt University (Scotland) in partnership with STUDOR.

This practical product is installed on the single stack to protect the traps' seals from positive pressure (backpressure/positive transients). When installed in conjunction with a Maxi-Vent, the P.A.P.A. becomes a positive and negative protection device. In this configuration the units can be placed throughout the stack to provide complete protection to the drainage system.

The P.A.P.A. unit has been designed with practicality in mind. There are no health and safety issues, as the units are one-person portable. The units are not mechanical devices and are built to last.

The units can easily be retrofitted into a current system to solve existing problems, or to add extra protection to the system against the transients in the system, and thus protect the traps on the branches from the pressures that occur in the stack.

The only reason for the requirement of an open vent as part of a drainage system design is to relieve any positive pressure in the system when AAVs are being used to relieve the negative pressures in the system. The P.A.P.A. is the final part of the solution to simplify drainage venting without the need to extend an open pipe vent to the atmosphere.

Using the complete "STUDOR System" a building's drainage system can be designed without roof penetrations. The Mini-Vents will protect the fixtures on the branch of the system and the P.A.P.A., together with a Maxi-Vent, will protect the stack against positive and negative pressures. The combination of AAVs and P.A.P.A. provide a perfect balance in returning the drainage system back to atmospheric pressure without any traps being siphoned.

For further information on the P.A.P.A. please contact 's Technical Manager, Steven White (steve@studor.net).
