Products Description

FH0301 / FH0302 Bullet-Type PU Earplugs (Without Cord / With Cord)

Brand: SATA | Product: Bullet-Type PU Earplugs Series | Standard: EN352

The bullet-type PU earplugs are made of SATA SS (Super-Soft) polyurethane material with slow rebound and strong self-shaping ability. The bullet contour and soft material provide comfortable fit and good sealing and sound insulation. Available in without-cord and with-cord configurations, they meet different needs for portability and loss prevention in machining, maintenance, stamping and other noisy environments.

Model Function Comparison

Model	Configuration	Main Features
FH0301	Without cord	SS PU material, bullet design, good sealing and sound insulation, anti-fouling surface.
FH0302	With cord	Based on FH0301 with easy-break cord to prevent tangling and loss.

Key Features

SS (Super-Soft) Polyurethane Material

SS PU material provides slow rebound and strong self-shaping ability, allowing gradual adaptation to different ear canal shapes for long-term comfort.

Bullet Contour Design

Bullet-shaped profile ensures comfortable fit and uniform contact with the ear canal, providing good sealing and sound insulation.

Anti-Fouling Surface Treatment

Surface is treated to resist soiling, making it easy to clean and maintain for hygienic use.

Easy-Break Cord Design (FH0302)

The with-cord model features an easy-break cord design that helps prevent tangling and reduces the risk of losing earplugs during frequent donning and doffing.

Applications

Machining & Maintenance: Lathes, milling machines and grinders often generate 85–95 dB(A)work.
Stamping & Sheet Metal Work: Stamping, bending and cutting processes with high noise levels requiring extended protection.
Equipment Commissioning & Overhaul: Around compressors, pumps and fans with continuous mechanical noise.
Tight Spaces & Frequent Removal: FH0302 with cord is suitable where earplugs are frequently removed and loss prevention is important.
General Industrial Noise: Workshops and production lines with noise levels around 85–100 dB(A).

Protection Standard Explanation (EN352)

Item	Description
Standard	EN352 series hearing protectors standards, specifying requirements for sound attenuation, comfort, construction and marking.
Attenuation Performance	Standardized testing provides attenuation values and standard deviations at different frequencies for evaluating protection in real-world use.
Applicable Noise Environments	Suitable for industrial steady-state noise. Hearing protection should be considered when noise exceeds 85 dB(A)work.

Frequently Asked Questions

Q: What is the difference between FH0301 and FH0302?

A: They share the same material and protection performance. FH0301 is without cord, suitable for straightforward distribution and cost-sensitive situations. FH0302 has a cord, ideal where frequent removal and loss prevention are concerns, such as inspections and multi-station tasks.

Q: How do I use the attenuation data table?

A: The table gives attenuation values and standard deviations at different frequencies. It helps evaluate protection for specific noise spectra. In practice, combine this with workplace noise measurements and aim to keep protected ear noise levels below about 75–80 dB(A).

Q: Can these earplugs be washed and reused?

A: These are designed as single-use devices and are not intended for washing and reuse. Replace them when they become deformed, hardened or visibly soiled.

Q: How should they be fitted?

A: Roll the earplug between clean fingers to compress it. Reach over your head with the opposite hand to pull the ear up and back, insert the earplug into the ear canal and hold for about 10 seconds until it expands and seals. Most of the earplug should be inside the ear canal with no visible gaps.
