• PP4-72A型聚丙烯離心通風(fēng)機(jī)

   PP4-72A型聚丙烯離心通風(fēng)機(jī)參照金屬4-72性能參數(shù)采用聚丙烯板，加熱壓模焊接而成。其廣泛應(yīng)用于科研、化工、冶金、電子、醫(yī)藥、紡織、儀表、電鍍、礦山、學(xué)校酒店、賓館、實(shí)驗(yàn)室、環(huán)保配套設(shè)備等行業(yè)中作通風(fēng)換氣排除酸堿性等有害氣體通風(fēng)之用。但不允許輸送含芳香族化合物、脂肪族與芳香族碳?xì)浠衔锏柠u素衍生物、酮類等腐蝕性氣體。具有耐化學(xué)腐蝕、不易老化、比重小、機(jī)械振動(dòng)小、噪音低、運(yùn)轉(zhuǎn)平穩(wěn)等特點(diǎn)。其所輸送氣體不允許含有粘性物質(zhì)、所含粉塵及硬質(zhì)顆?！?50mg/m3、氣體溫度50℃、相對(duì)濕度≤100%。且避免陽光暴曬、風(fēng)機(jī)現(xiàn)場(chǎng)附近不得有熱源。

• PP4-72A polypropylene centrifugal fan series

   The PP4-72 polypropylene centrifugal fan is made of polypropylene plate and heating die according to the metal 4-72 performance parameters. It is widely used in research, chemical, metallurgy, electronics, medicine, textile, instrumentation, electroplating, mining, school hotels, hotels, laboratories, environmental protection equipment and other industries for ventilation and ventilation to eliminate harmful gases such as acid and alkali. . However, it is not allowed to transport a corrosive gas such as a halogen derivative containing an aromatic compound, an aliphatic or an aromatic hydrocarbon, or a ketone. It has the characteristics of chemical corrosion resistance, aging resistance, small specific gravity, low mechanical vibration, low noise and stable operation. The gas to be transported is not allowed to contain viscous substances, dust and hard particles ≤150mg/m3, gas temperature 50°C, relative humidity ≤100%. And avoid sun exposure, there must be no heat source near the fan site.
