我们的ASHRAE 52.2除尘器的设计和制造符合ASHRAE 52.2标准，可将灰尘加载到空气过滤器中。 它坚固耐用，持久耐用。 在我们的日常空气过滤测试中，我们使用粉尘进料器在15年的粉尘进料中验证了设计。

Our ASHRAE 52.2 Dust Feeder is designed and manufactured to meet the ASHRAE 52.2 standard for loading dusts to air filters. It is rugged and long lasting. We have validated the design from our 15 years of dust feeding using the dust feeder in our daily air filtration tests.

LMS dust feeder handles all types of dust, such as ASHRAE 52.1 and 52.2 dusts, SAE fine, coarse and ultrafine, LMS dust and many more. Principal of operation is venture.

The overall footprint is: 36” long x 9” wide x 15” high (92x23x38 cm)

Unit is calibrated for 10 minutes interval but this could be as high as 20 minutes.

The wheel is guarded by metal/plexi glass chamber to prevent any injury to fingers.

The venture is guarded with a plexi-glass chamber to prevent any damage to the venture nozzle by the end user.

The dust feed range with good accuracy is 0.1-6 grams/minute. The dust feeder could handle lower or higher dust feeds but with lower accuracy.

LMS除尘器可处理各种类型的粉尘，例如ASHRAE 52.1和52.2粉尘，SAE细粉，粗粉和超细粉尘，LMS粉尘等等。 

设备尺寸：36英寸长×9英寸宽×15英寸高（92x23x38厘米）

设备的校准间隔为10分钟，但可能高达20分钟。

轮子由金属/树脂玻璃室保护，以防止手指受伤。

精确度高的粉尘进料范围为0.1-6克/分钟。 除尘器可以处理更低或更高的灰尘，但精度较低。
