GDE Series

Choosing a dust collector

Select the model of the dust collector based on the required air flow. Check the required air flow in the following order.

Checking the type of dust and generating source

Check the type of dust (to see if it can be sucked in by the GDE series) and the source of the dust.

Determining the type of hood and installation method

Take workability into consideration and examine the type of hood to use and how it is going to be installed. Ensure that dust can be collected at a distance X [m] as close as possible to the source of the dust.

Check the control air speed

The control wind speed to derive the performance of the local exhaust equipment according to the model of the hood is stipulated in the Ordinance on Prevention of Hazards Due to Dust.

Control wind speed stated in the dust impairment prevention regulations (Ordinance on Prevention of Hazards Due to Dust)

Control air speed according to the provisions in the standards under Article 27 Para 1 of the Ordinance on Prevention of Hazards Due to Dust

Model of hood Control air speed (m/s)
Enclosure-type hood 0.7
Externally-mounted hood lateral suction type 1.0
Bottom suction model 1.0
Upper suction model 1.2
Remark
  1. The control wind speed in this table refers to the control wind speed when all the hoods of the local exhaust equipment which may be used at the same time are open.
  2. The control wind speed in this table refers to the respective wind speeds given below according to the model of the hood.
    1. Minimum wind speed at the opening side of the hood for an enclosure-type hood.
    2. Wind speed at a work position among the work positions pertaining to the dust source that is the farthest from the opening side of the hood and within a range where scattered dust is sucked in by the hood for an externally-mounted hood.

Control wind speed of a machine having a rotating body like a grinding machine or drum sander etc. pursuant to the provisions in Article 4 or Article 27 Paragraph 1 of the Ordinance on Prevention of Hazards Due to Dust

How to install the hood Control air speed (m/s)
How to enclose an entire machine having rotating bodies 0.5
In this method, the dispersion direction of the dust generated by the rotation of the rotating body is covered at the opening side of the hood 5.0
How to enclose only the rotating bodies 5.0
Remark
  1. The control wind speed in this table refers to the control wind speed when all the hoods of the local exhaust equipment which may be used at the same time are open.
  2. The control wind speed in this table refers to the minimum wind speed at the opening face of the hood when the rotating body is stopped.

Calculating the required air flow

The required air flow is calculated from the type and shape of the hood and the control wind speed was determined in the preceding paragraph.

Model of hood Sketch Airflow Q(m3/min)
Enclosure-type Q=60·A·Vo
=60·A·Vc

Vo:Average wind speed at the opening face[m/s]
Vc:Control air speed[m/s]

External type
(Rectangular or circular canopy hood)
Q=60·VC·(10X²+A)
External type
(Circular or rectangular hood with flange provided in free space)
Q=60·0.75·VC·(10X²+A)
External type
(Circular or rectangular hood provided in free space)
Q=60·1.4·P·H·Vc

GDE Series

GDE Series models are equipped with an ultra-fine filter backed by Apiste's cutting-edge ultra-fine nanofiber technology.
Apiste ultra-fine filters work together with our Green Pulse System to eliminate the need for filter replacement over the long-term and achieve cleaner emissions than any dust collector so far.
GDE Series dust collectors are equipped with an energy-saving Premium Efficiency Motor, an inverter for auto-airflow control, memory for storing operating data, remote operation functions, and more.
