With a history of nearly 30 years, Doguan Retop Filter Material Co., Ltd. (hereinafter referred to as Retop Filter Material) has dedicated itself to the development and production of specialised filter materials in the sector. As a renowned supplier of filter materials, Retop Filter Material has chosen the Palas® MFP Nano Plus 4000 for clear determination of the separation efficiency of HEPA and ULPA filter media in accordance with DIN EN 1822-3 and ISO 29463-3 and in the MPPS range. Palas® is an industry leader of aerosol and particle measurement technology and meets a wide range of production requirements. Retop is focused on environmental engineering, laboratory research, automotive and industrial sectors, for which Palas® has the know-how and experience to provide professional solutions.
The professional choice
Retop Filter Material provides filtration and separation solutions in five areas, namely automotive air conditioning, fuel cell air intake, clean purification, HVAC industrial filtration and mask protection. Its materials are designed for OEM, OES as well as aftermarket applications. With an annual production capacity of over 60 million square meters of various automotive filtration nonwovens, it is one of the largest manufacturers of automotive filter media in China. As a global supplier, Retop Filter Material has established strategic partnerships with many renowned filter brands and automotive companies at home and abroad. To meet the different production requirements of customers, the company is in urgent need of accurate and reliable testing devices for product performance evaluation and quality control. The choice of Palas® means that rigorous attention to details and the highest quality are always present in the development and production of Retop products.
The reliable Palas® instruments
Before choosing Palas®, Retop Filter Material used instruments that were not adequate for meeting the actual demands and challenges of the market. In addition, the company embarked on a project that required determination of fraction separation efficiency of nanoscale particles according to EN 1822-3 and ISO 29463-3. This necessitates the use of more accurate instruments to fulfill production requirements. Retop has long heard about the professional testing equipment of Palas®, and started a technical research after meeting Palas® at an industry exhibition. Having compared Palas® products with other offers in the market, Retop made its final decision to purchase Palas® MFP Nano Plus 4000.
In actual use, Palas® provides Retop Filter Material with more accurate and reliable data and even better-than-expected monitoring results. Mr. Yan Yixu, General Manager of Retop Filter Material, said: “To produce outstanding products is not possible without reliable instruments. With Palas® instruments, we make sure that our products are trustworthy and reliable, winning the recognition of our key clients in the market. ”
The stable Palas® monitoring
The Palas® MFP Nano plus 4000 test rig has been proven and tested by many users worldwide with convincing competence and reliability for quality management. The MFP Nano Plus 4000 series is specially designed for clear determination of the separation efficiency and MPPS (Most Penetrating Particle Size) range of HEPA and ULPA filter media in accordance with DIN EN 1822-3 and ISO 29463-3. The test rig is equipped with a scanning mobility particle sizer, a powerful nanoparticle measurement and analysis device with a measurement range of 10nm – 800nm for particle size measurement and analysis. The MFP Nano Plus 4000 uses two UF-CPC in raw and clean gas and detection of MMPS range to measure efficiency at various particle sizes.
MFP Nano plus 4000
Benefits
· Real-time determination of the fraction separation efficiency above 10 nm
· The measuring time for determining the fraction separation efficiency is halved by measuring the particle concentration in the raw and clean gas.
· No dilution necessary!
· Combining two UF-CPC versions, the UF-CPC for the highest concentrations up to 2,000,000 particles/cm3 (single count mode) in the raw gas and the UF-CPC 50 for top counting rates at low concentrations in the clean gas, corresponds to a dilution factor of 1:200.
· Internationally comparable measurement results in accordance with DIN EN 1822-3 and ISO 29463-3
· Simple use of different test aerosols, such as NaCl / KCl or DEHS (others on request)
· Simple measurement of the fraction separation efficiency and determination of the MPPS range
· High reproducibility of the test method
· Flexible filter test software FTControl
· Easy to operate, even untrained personnel can be quickly trained in the use of the equipment
· Cleaning can be performed independently by the customer
· Short set-up times, fast throughput times
· Mobile set-up, easy to move on castors
· Clear verification of the function of the individual components and the system as a whole in the scope of pre-delivery acceptance testing and at delivery
· Reliable functioning
· Little maintenance required
· Reduces your operating expenses
Applications
· In accordance with DIN EN 1822-3 (HEPA / ULPA) and ISO 29463-3 standards, test filter materials and small/micro filters in product development and production quality management
· Complete the measurement of the separation efficiency of particles below 1μm for other filter materials
