1/ What is the E.M.P-Japan CM-15-24 DC air pump?

The CM-15-24 is a compact, direct-current air pump capable of both suction and discharge, designed for medical and light industrial applications. It requires no additional assembly and is built by E.M.P-Japan Ltd.

2/ What is the maximum flow rate?

The pump delivers a flow rate of at least 1.5 L/min (0.05 cfm), ensuring stable air delivery for devices such as sphygmomanometers and inkjet printers.

3/ What is the maximum discharge pressure?

It can generate a discharge pressure of at least 26.6 kPa (3.87 psi), allowing reliable air supply in various medical and industrial equipment.

4/ What is the maximum vacuum level?

The CM-15-24 attains a vacuum down to –26.6 kPa (–200 mmHg), enabling effective suction for applications like wound drainage or negative-pressure devices.

5/ What are the electrical requirements?

Rated voltage: DC 24 V

No-load current: 0.06 A

These specifications help integrate the pump into low-power systems without heavy power supplies.

6/ What insulation class and ambient conditions are supported?

The pump features Class E insulation and operates reliably in ambient temperatures from 0 °C to 40 °C, making it suitable for laboratory, clinical, and factory environments.

7/ What materials contact the pumped gas?

All gas-contacting parts are made of chloroprene (CR) rubber and polybutylene terephthalate (PBT), which resist mild chemicals and meet medical-grade cleanliness standards.

8/ What are the connection size, weight, and dimensions?

Connection port: φ 5.5 mm hose fitting

Mass: 0.06 kg

External dimensions: 31 × 74 × 23.5 mm

Its small footprint and light weight simplify installation in space-constrained devices.

9/ Which applications commonly use the CM-15-24?

Sphygmomanometers (blood pressure monitors)

Medical examination and diagnostic equipment

Dental treatment devices

Inkjet printers

Its dual suction/discharge capability and compactness fit a wide range of precision instruments

10/ How should I maintain the CM-15-24 for long life?

Keep the inlet/outlet ports free of dust and debris

Wipe the exterior with a soft, dry cloth; avoid solvents
