Two kinds of trial air filters are producted and the performances of them are experimentally examined. First, trial filters, designed on the theory of inertial dust collection, are produced. Ash collection coefficients are examined using volcanic ash collected from several places around Sakurajima. The overall ash collection coefficients are between 70% to 90% for eliminators with grooves, 65% to 85% for eliminators without grooves, when the air velocity is less than 4m/s. The partial ash collection coefficients, corresponding to the ash diameter regions 0-75,75-125,125-250,250-500 are 22%, 75%, 98% and 100%, respectively, when the air velocity is 3m/s. It is verified that the overall ash collection coefficients synthesized from the partial collection coefficients are similar to those measurements. Next, the efficiency of a wet type ash filter is examined. The ash collection coefficient by this filter is more than 97%. However, as wet ash gradually sticks on the eliminator with water spraying, which will eventually require the maintenance, it can only be recommended to use in the restricted area where the influence of ash is remarkable.

研制了两种试验用空气过滤器，并对其性能进行了试验研究。首先，制作了基于惯性集尘原理设计的试验过滤器。利用从樱岛周围几个地方收集的火山灰来检验火山灰收集系数。当风速小于4m/s时，有槽除尘器的总集灰系数为70% ~ 90%，无槽除尘器的总集灰系数为65% ~ 85%。风速为3m/s时，0 ~ 75、75 ~ 125,125 ~ 250,250 ~ 500灰径区对应的部分集灰系数分别为22%、75%、98%和100%。经验证，由部分集灰系数合成的总集灰系数与测量值相近。其次，对湿式灰滤机的过滤效率进行了研究。该过滤器集灰系数大于97%。但湿灰随着喷水逐渐粘在除灰器上，最终需要维护，只能建议在灰影响显著的限制区域使用。
