Products Description

HF0101V / HF0301V Foldable KN95 Particulate Respirators (With Valve)

Brand: SATA | Product: Foldable KN95 Particulate Respirator (With Valve) Series | Standard: GB2626-2019 KN95

This series of non-powered air-purifying particulate respirators includes ear-loop and head-strap versions with exhalation valves. The valve helps discharge heat and moisture, reducing exhalation resistance for improved comfort during extended use. They feature a 5-layer high-efficiency, low-resistance structure for protection against non-oil particulates.

Model Configuration Overview

Model	Wearing Style	Valve	Key Features
HF0101V	Ear-loop	Yes	5-layer structure; exhalation valve discharges heat and moisture; includes S-hooks.
HF0301V	Head-strap	Yes	Wide knitted head strap for comfort; exhalation valve reduces breathing resistance.

Key Features

Exhalation Valve Design

The exhalation valve opens during exhalation to discharge humid air and heat, reducing exhalation resistance and improving comfort, especially for long-duration or high-intensity work.

5-layer High-efficiency Low-resistance Structure

Both models use a 5-layer structure with non-woven fabric, electrostatic cotton, and melt-blown fabric, providing ≥95% filtration efficiency against non-oil particulates.

Good Fit and Seal

Adjustable internal nose clip combined with a sponge nose pad ensures a tight facial seal to reduce leakage.

Applications

Hot or long-duration work: Summer outdoor work, foundries, etc., where the valve reduces stuffiness.
High-intensity labor: Construction, forestry, etc., where reduced breathing resistance is beneficial.
General industrial dust: Grinding, sweeping, material handling with non-oil particulates.

Frequently Asked Questions

Q: What is the difference between valved and valveless respirators?

A: Valved respirators use a one-way exhalation valve to discharge warm, humid air, reducing resistance and improving comfort for long or heavy work. Valveless models are simpler and suitable for short-term use.

Q: Can valved respirators be used in medical or epidemic settings?

A: Not recommended. The exhalation valve allows unfiltered exhaled air to escape, which could pose a risk to others. Therefore, they are typically prohibited in sterile environments like operating rooms and are not recommended for general public use during epidemics.

Q: Does the valve affect filtration efficiency?

A: No. The valve only opens during exhalation. During inhalation, the valve is closed, and air passes through the filter material. Thus, the valve does not reduce the wearer's protection.

Q: Can these respirators reduce odors?

A: HF0101V/HF0301V are standard filter models without an activated carbon layer, so they have limited effect on reducing organic vapors, ozone, or other odors. For odor relief, choose activated carbon models (e.g., 530104V/530204V).

Q: How should I maintain the exhalation valve?

A: This is a single-use respirator. Do not disassemble or clean the valve. Replace the entire respirator if the valve is damaged or blocked.
