HR8050H24B DC Brushless Blower for Particle Counter Sampling Systems

Project Overview

A particle counter manufacturer was developing a new generation of portable cleanroom monitoring instruments. The original sampling pump used in the system delivered acceptable performance, but the customer faced increasing pressure from long lead times, high procurement cost, and limited flexibility for mechanical redesign.

The customer needed a compact 24V DC blower that could support stable air sampling, fit into a limited internal space, and offer better supply flexibility for future mass production.

Herays recommended the HR8050H24B DC vortex blower as an alternative solution for evaluation.

Customer Background

The customer produces particle counters used in controlled environments such as pharmaceutical cleanrooms, electronics manufacturing, medical device production, HVAC inspection, and laboratory air quality monitoring.

Their instruments require stable airflow through an optical sensing chamber. Any instability in the sampling airflow can affect particle counting accuracy, repeatability, and calibration performance.

Because the air-moving component is critical to the entire measurement system, the customer needed a replacement solution that could be technically evaluated before being introduced into production.

Challenge

The customer was looking for an alternative to an AMP45-type sampling pump used in a particle counter air path.

The main challenges included:

• long and uncertain delivery time from the original pump source
• rising component cost
• limited flexibility in mounting and mechanical layout
• need for stable airflow in a compact sampling system
• requirement for 24V DC operation
• need for faster engineering response during prototype development
• concern about future mass production supply continuity

The customer did not simply want a cheaper component. They needed a blower that could become part of a reliable long-term product platform.

Application Requirements

The blower had to meet several practical requirements for particle counter integration:

Herays recommended the HR8050H24B DC vortex blower for prototype evaluation.

The HR8050H24B was selected because it offered:

• 24V DC operation
• compact vortex blower structure
• strong airflow performance
• suitability for particle counter sampling systems
• better cost-effectiveness
• faster sample and project response
• OEM customization potential
• flexible mechanical integration support

Instead of treating the project as a simple one-to-one pump replacement, Herays worked with the customer from an application perspective. The blower was evaluated together with the customer’s air path, internal space, flow resistance, and system performance requirements.

Why HR8050H24B Was Recommended

The HR8050H24B was a strong candidate for the project because particle counters require more than airflow alone. They require a blower that can work reliably inside a controlled measurement system.

Key advantages included:

Implementation Process

The project was handled in several steps.

1. Requirement Review

The customer provided information about the existing pump, target sampling flow, installation space, and expected performance. Herays reviewed the air path structure and confirmed that HR8050H24B was suitable for sample evaluation.

2. Model Recommendation

Based on the 24V system requirement and particle counter application, Herays recommended HR8050H24B as the first test model.

3. Sample Testing

Samples were prepared for customer testing. The customer evaluated airflow, pressure, operating noise, installation feasibility, and system compatibility.

4. Mechanical Review

Because the customer’s particle counter had limited internal space, the mounting structure was reviewed carefully. The HR8050H24B provided better flexibility for customized installation compared with the original pump structure.

5. Production Planning

After initial evaluation, the customer continued communication with Herays regarding future sample batches, customized requirements, and supply planning for mass production.

The HR8050H24B helped the customer build a practical alternative path for the particle counter sampling system.

Key results included:

• reduced dependence on a single imported pump source
• improved supply flexibility for future production
• lower projected component cost
• practical 24V DC blower option for prototype testing
• faster communication during engineering evaluation
• clear path for OEM customization
• stronger confidence in long-term sourcing stability

The customer gained an alternative blower solution that could be evaluated not only for one model, but also for future particle counter platforms.

Technical Notes

For particle counter applications, final performance depends on the complete air system, not only the blower.

During evaluation, engineers should check:

• target flow rate
• system pressure resistance
• filter loading effect
• flow sensor feedback
• noise and vibration
• thermal performance
• power supply stability
• mounting structure
• calibration consistency
• long-term operating life

Herays can support customers during this evaluation process by recommending suitable HR series blower models and discussing customization options.

Product Used

Customer Value

The customer’s biggest gain was not only finding another blower. They gained a more flexible supply and engineering support path.

For particle counter manufacturers, this matters because cleanroom monitoring instruments often have long product lifecycles. Once a blower is designed into a system, stable supply becomes just as important as initial performance.

The HR8050H24B gave the customer a practical way to improve:

• component sourcing security
• product cost structure
• engineering flexibility
• supplier response speed
• future customization options

Conclusion

The HR8050H24B DC vortex blower provides a practical solution for particle counter manufacturers looking for an AMP45-type pump alternative.

With 24V DC operation, compact structure, strong airflow capability, and OEM customization support, HR8050H24B can help cleanroom monitoring equipment manufacturers reduce supply chain risk and improve long-term product competitiveness.

For OEMs developing or upgrading particle counters, Herays can provide sample support and technical communication to help evaluate whether HR8050H24B fits the target sampling system.
